Answer: Friedman's ANOVA
◉ Which parametric test compares two sets of scores generated
through a repeated measures design?
Answer: wilcoxon signed rank test

Answer: Mann whitney u & wilcoxon rank sum test
◉ What is pearson's r?
Answer: Pearson's r is a correlation coefficient (r) used as a measure
of effect size
◉ What does pearon's r range from?
Answer: -1 to +1
◉ What does a -1 and +1 pearson's r represent?
, Answer: -1 represents a perfect negative correlation and +1
represents a perfect positive correlation
◉ Fill in the blanks.
The closer r is to zero the () the correlation is
Answer: weaker
