Answer to Question 1

ANS: B

Feedback
A The mean as an average represents interval- and ratio-level data.
B The category with the highest frequency is the mode and is used often with nominal-level data.
C The median is the middle score or the score when 50 of the scores are above it and 50 of the scores are below it.
D Percentile represents the percentage of cases a given score exceeds.

Answer to Question 2

ANS: B

Feedback
A Overlap is eliminated by defining the size of the group or interval width so that no score falls into two groups.
B Very large interval widths lead to loss of data information and may obscure patterns in the data.
C Frequency intervals do not generate means.
D Data or a score generated on a variable will fit into one frequency interval defined by the investigator.
