1) Review the paired samples t test equation below and answer the questions: 1a. What is d with the bar over it called and how do you find it? 1b. What is the S (with subnotation of d) called? 1c. What is n? 2) What is the estimated standard error for a paired sample t test using the following data: Standard deviation of the difference score 5 and n-100? 3) In a paired samples t test, explain the logic of difference scores (why do you need to find them to make conclusions about your research) and why do you compare it to a population mean often designated as zero (u-0)?

Transcribed Image Text:1) Review the paired samples t test equation below
and answer the questions:
1a. What is d with the bar over it called and how
do you find it?
1b. What is the S (with subnotation of d) called?
1c. What is n?
2) What is the estimated standard error for a paired
sample t test using the following data: Standard
deviation of the difference score 5 and n-100?
3) In a paired samples t test, explain the logic of
difference scores (why do you need to find them
to make conclusions about your research) and
why do you compare it to a population mean
often designated as zero (u-0)?
