Answer 1

central tendancy

Question 2

• measure of normal variability
• average difference of scores from the mean score

Answer 2

standard deviation

Question 3

• the standard deviation that would be obtained if
  
  • a person of average ability took the test a large number of times and their scores were plotted
• tells the confidence of the test score

Answer 3

Standard Error of Measurement (SEM)

Question 4
