Question

To learn whether there are significance between two independent groups on some measure, you need to run _________ analysis in Microsoft Excel

1. Two-sample t-test

2. ANOVA

3. Paired t-test

4. Correlation

Expert Solution
Step 1

To learn about whether there exists a significant difference between two independent groups on some measure, the Two-sample t-test is used.

Assuming that the samples are taken from two different population which are normally distributed. Also assuming that the two population have the same variances, the test statistic is given by

     t=|M1-M2|-|μ1-μ2|Sp1n1+1n2~tn1+n2-2

where M1 & M2 are the means of two samples of sizes n1 & n2 respectively.

And Sp is the pooled standard deviation given by 

  Sp=n1s12+n2s22n1+n2-2
