The Analysis of Variance (ANOVA) is a hypothesis test to compare the means of more than two populations. For more free math videos, visit: http://www.professorserna.com
Here, I explain the steps of the ANOVA Complete Randomized Design: 1)Setting up the Null hypothesis that all the means are equal and the Alternative hypothesis that at least two mean differ. 2) Calculation of the test statistics (the actual calculations are done in the next video of this series). 3) Finding the rejection region using the F distribution. 4) Making the decision whether to reject or not to reject Ho and 5) Writing the conclusion.

Technically you should say Fail to Reject Ho because you have determined there is a lack of evidence against Ho. You have not proven Ho in any significant way. With that said, many introductory courses teach students that they can conclude that we Accept Ho. Please be aware of the nuance regardless of how you choose to phrase the conclusion.
Reject Ho, however, is a stronger statement that we can justifiably make using the laws of probability and the level of significance of the test. When we Reject Ho we are concluding that there is enough evidence against Ho with the state level of significance used. We are willing to accept the chance of making a Type I Error, but we are very clear about the probability of its occurrence, i.e., it is equal to alpha (at least nominally).

When measuring groups with ANOVA, there are two sources of variance: between and within. Variance between groups is due to actual treatment effect plus differences due to chance (or error). Variance within the groups is due only to chance (or error). This is the variance that we are analyzing.

“Now let’s talk about the UGLY variances, which are the overhead variances!”
In the video, 5.03 - Overhead Variances – Lesson 1, Roger Philipp, CPA, CGMA, reviews the components of manufacturing inventory which includes, direct materials, direct labor and factory overhead. All of these components can be analyzed for spending, efficiency and volume variances.
Roger also emphasizes the flexible budget equation, which is the basis for all overhead variance analysis. Going into an example from the course BEC textbook, he describes a situation with an allocation base of 100,000 direct labor hours at budgeted production level, budgeted fixed rent of $400,000 and budgeted variable cost of $1 in electricity for each direct labor hour. Of course Roger plugs these budgeted numbers into the flexible budget equation, then goes into the actuals: fixed rent was not-so-fixed at $390,000 and electricity ended up costing $1.01 an hour. Most importantly, actual direct labor hours is 97,000 but standard direct labor hours at budget for the actual level of production is 96,000.
Understanding the last point is important, so Roger writes it up on the whiteboard, and warns us we’ll be using all of these direct labor hour numbers in the upcoming variance analysis!

Video Transcript Sneak Peek:
OK, now let's talk about the ugly variances, which are the overhead variances. And this is something that even though you just studied it in school, you probably just prayed that the exam wouldn't be tough, and you hopefully got through the exam.
What we're looking at here with overhead... Now remember with overhead we said we've got direct materials, direct labor and factory overhead. With overhead we have spending, efficiency, volume. Something that's important to understand is all of your overhead variance analysis is done using the flexible budget equation. What was the flexible budget equation? Total cost equals fixed plus variable times X. So as we go through and we look at these, we're gonna be looking at fixed plus variable times X, where X is gonna be changing as we go across.

How to run and interpret the results of a MANOVA in SPSS is covered in this video (part 1).
Video Transcript: So let's go ahead and get started with our problem in SPSS. Now in SPSS you can see here we have three variables, gender, where we have males and females; I can turn those value labels off for a minute. We have males and females given by 1s and 2s, and we have our two dependent variables, empathic concern and cognitive perspective taking. So notice here we have to have at least two variables once again for MANOVA, so you can see those here, and then we have our grouping variable which is gender. So let's go ahead and run the MANOVA. So to do that we want to go to Analyze and then General Linear Model and then Multivariate. And here the Multivariate dialog box opens. We're going to take our two dependent variables, empathic concern and perspective-taking, move those over to the dependent variables box, and I just pressed and held the control key to grab both of those at once, and then move gender to Fixed Factor(s). And then let's go ahead and go to Options, select gender and move that over to the Display Means for box, check on Descriptive statistics, Estimates of effect size, and Homogeneity tests, and then click Continue and then go ahead and click OK. Next we get our results out, and you can see here our first table shows us our Between-Subjects Factors, and here we have gender, 1 and 2, 1 is male 2 is female, and notice we have 15 adolescents in each group. Next is our Descriptive Statistics table. We have empathic concern for males and females, so here's these two means, and notice in the sample, let's just go ahead and go through this and ask yourself, which of the two genders scored higher on empathic concern? Now we don't know if this is significant yet, but just descriptively, just visually inspecting. Notice that females scored higher than males by 8.27 points, approximately, on empathic concern. And then here on perspective-taking, we can see that females scored about almost three points higher on perspective-taking than did males. OK next we have Box's Test for Equality of Covariance Matrices. Now this test tests an assumption of the MANOVA, which is that the variance-covariance matrices, also referred to as the covariance matrices, as you see here, are equal for the two groups. Now we're going to have a separate video on this assumption to look at it in more detail, but basically in a nutshell it's very similar to the equal variance assumption for the ANOVA; this assumption is the multivariate generalization or extension of the assumption of equal variances for the ANOVA, it's testing the corresponding variances and covariances are equal for the two groups. But for now all you really need to know is that we want to look at our p-value here and we hope that this is greater than .05. But in fact this test, Box's test the equality of covariance matrices, is so sensitive to departures from non- normality, that a lot of people will even use a standard of p is greater than .001. So, basically, we want this result to be not significant. So if we use the more lenient standard and use p is greater than .001, then you can clearly see, well at either level (.05 or .001), this is not significant. So that provides us some evidence that the variance-covariance matrices are equal for the two groups. And that's an assumption of MANOVA, we want that to hold. So, unlike our significance tests on means, we want this to be greater than .05 or greater than .001. And in that other video I'll go into more detail, some of the subtleties of that, and the research findings as well, and what we can do if we do have a p-value that's less than say, .001, for Box's test. OK next we'll go to our Multivariate Tests box

A step-by-step introduction to MANOVA in SPSS is covered in this video (part 3).
Video Transcript: now remember that for these two tests here we're using the alpha of .025 per test. We're not using alpha .05 per test, but instead we're using that Bonferroni adjusted level. So our first result, the empathic concern, this is a p of .015, and that is less than .025, so that result is significant. So this indicates that boys and girls differed on empathic concern. Looking at our next result, we see a p of .138, which is not less than .025, so this result is not significant. So, in other words, there was not a significant difference between boys and girls on perspective taking. So we want to summarize these results in just a minute in our written results, but before we do that, empathic concern was significant and recall earlier I had said if there was a significant result for ANOVA that we want to go ahead and look at the means so we can describe the differences. So we can look at our Estimated Marginal Means table if we'd like. We also saw the means earlier in the Descriptive Statistics table, right here. But let's go and look at the other table for practice as well. So down here at Marginal Means, empathic concern was significant, it had that p of .015 recall. So here we see that males and females, there's the two means. So which group had the higher mean? Females, right? So females had significantly higher or demonstrated significantly higher empathic concern than did males. But as far as perspective-taking was concerned, there was not a significant difference between males and females. So next we'll write those results up using APA format. OK now going back up to our Multivariate Test table, remember we're going to use Wilks' Lambda. And here notice first of all that Wilks' Lambda has a value of of .741, an F of 4.73, rounding, degrees of freedom of 2 and 27, a p-value of .017 as we saw before, and then partial eta-squared, rounding to two decimal places, of .26. So I'm going to use all of that information in the written results here. So the first sentence, I say there was a significant difference between males and females when considered jointly on the variables in empathic concern and perspective taking. And then here we have Wilks', and this is the Lambda, this symbol here, is equal to .741, and you saw that right here, and then F 2, 27. From here on out this part looks like a normal ANOVA. F 2 and 27, so here's the degrees of freedom, 2,27 equals 4.73, which you see right here rounded to two decimal places, and then finally p of .017, which is right there, and then partial eta-squared of .26. OK, so that first sentence shows the multivariate result, or the MANOVA. And then next we have a separate ANOVA was conducted for each dependent variable

The assumptions for One-Way ANOVA require a scale-level dependent variable and a categorical independent variable, typically with three or more levels. Check for outliers, independence, and normality. The non-parametric alternative is the Kruskal-Wallis One Way ANOVA test. The null hypothesis for ANOVA is that the means are the same.

One important assumption of the Independent-Samples t Test is that the variances in the sample groups are approximately equal or that the samples have homogeneity of variance. Levene’s Test for Equality of Variances is a test of whether the variances of the two samples/groups are approximately equal. You will learn how to conduct Levene’s test in SPSS both within an independent samples t test and using the Explore command.
This video updated Jan. 2018 to correct the video and audio about p values.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more.

This tutorial shows how to use the statistics application SPSS (formerly known as PASW) to compare the means of several groups (3 in this case) on a single quantitative outcome using a one-way analysis of variance (ANOVA). It also shows how to perform a post-hoc analysis using the Tukey test (or Tukey HSD test, for Honestly Significant Difference).

Video Transcript Sneak Peek:
In order to do overhead variances, here's what we're going to do. As I said, all the variances are done in the flexible budget equation. What was the flexible budget equation we’ve learned in the past?
We learned total cost equals fixed plus variable times x. That’s you're flexible budget equation. Fixed plus variable times x, total cost, for fixed, plus variable, times x. You’ve got your fixed overhead plus your variable overhead to...per hour, times x is your activity level. So x is some cost driver, some activity level.
So our flexible budget equation is total cost equals fixed plus variable times x. When you're doing flexible budget, when you do the budget, within a budget what costs are normally the same? Fixed or fixed? Remember, within the relevant range, fixed are fixed. Variable are fixed per unit. We're looking at the x, which is the cost driver, the activity level. So that's called our flexible budget equation. We're trying to figure out what total cost will be at different levels of activity, x being your cost driver.
So, for doing all of our overhead analysis using, so we’re always going to compare something with the flexible budget equation, and the way we're going to do this is, we're going to look at, on the left side, we're going to start here with our actual overhead. Actual overhead. We're going to compare that with our flexible budget equation at actual.
We're going compare that with our flexible budget equation at standard, and then we’re going to compare that with standard of standard. What is standard of standard. That's called applied. That’s your applied overhead. That's the overhead you applied into what? WIP. Whip it good! Remember that? WIP? Work in process. That’s the amount we applied into work in process.
So, with overhead, again, don’t lose sight of the big picture...What is overhead? All the other costs in the factory except which? Direct materials, direct labor. We already gave materials and labor. Now we’re looking at overhead.

How to perform a Brown-Forsythe and Welch F tests in SPSS. These tests are robust to violation of the homogeneity of variance assumption. I also show the degree to which these tests work at keeping alpha close to .05 across various conditions based on published simulation research.

What is homogeneity of variance and why is it important? I answer these questions. Also, I describe three different types of Levene's tests, two of which are robust to non-normal distributions and unequal sample sizes. Finally, I provide some brief guidelines relevant to how robust the t-test and ANOVA are to violations of the homogeneity of variance assumption.
Here's the link to the video where I demonstrate how to perform the three different levene's tests:
