variables?
[Enter your response here.]
2. Explain why you chose this test.

First perform an f-test to see if your data has equal or unequal variances by selecting Data > Data
Analysis Tool > F-Test Two-Sample for Variances.
Be sure to select the Labels box if your highlighted area includes labels.

Your output should look something like this:
Here we have unequal variances so we would choose t-Test: Two-Sample Assuming Unequal
Variances.

Next, highlight the cells we are using to perform the t-test. We are hypothesizing that there will be no
difference in the mean, so we set that to 0.

ANOVA in Excel
To run an ANOVA in Excel, select Data > Data Analysis, and then choose the appropriate ANOVA test:
Choose the variables you want to include (input range), select the Labels box if needed, and set your
alpha (usually at .05).

Chi-Square in Excel
Running Chi-Square in Excel is a little trickier. First, create a frequency table of the variables.
Highlight the table, select Copy, then go directly below and select Paste Special or Paste Values.

Relabel this table Expected and delete data inside the table (keep the total columns).
Next, we need to calculate the expected values.
Using this same method for all, multiply the column total by the row total, then divide by the grand total.
Column total * row total / Grand total (in bottom right corner of table) = Expected frequency

Continue until all expected frequencies are filled.
Next, we need to calculate the p. Type p to label your output, and then fill in the =chitest function by
highlighting the actual values in the top table and the expected values in the bottom table.

This results in a probability value that you will compare to your alpha (.05, or .01) to decide whether you
have a statistically significant difference. (Here we fail to reject our null hypothesis since .687>.05,
meaning that there is no statistically significant difference between our observed and expected
frequencies.)
