Expert Solution
Step 1
Given Information:
4 individuals were tested in the Memory test in the congruent condition.
Another 4 individuals were tested in the incongruent condition.
The data is:
| Group 1 | Group 2 |
| 10 | 20 |
| 6 | 12 |
| 9 | 15 |
| 3 | 9 |
Enter the data in Excel. Use the Excel function "=AVERAGE()" to obtain the sample mean for each group.
Use the function "=STDEV.S()" to obtain the sample standard deviation for each group.
