KIN 3502 Exam with Questions and
Correct Answers
Descriptive Statistics - ANS Mathematics used to organize, summarize, and describe data
Scales of Measurement - ANS Ration, Interval, Ordinal, Nominal
Nominal - ANS Taking information and creating categories
Ex. Classifying by what grade level
Ordinal - ANS Put in order, rank from highest to lowest, no math
Interval - ANS
Ratio - ANS
All data is C.R.A.P - ANS Categories - nominal
Ranking - ordinal
Arbitrary Zero - interval
Positive Scores - ratio
Frequency - ANS Rate at which something occurs (How many times?)
, Distribution - ANS How is the data spread? (Where is the data?)
Histogram - ANS Shows frequency (How many times the different values are
appearing in the data set)
Percentiles - ANS Represents the percent of observations at or below a given score
Range from 0-100
Norm-referenced
Mean - ANS Average
Median - ANS middle score or P50
Mode - ANS Most frequently observed score
Skewness - ANS distortion or asymmetry in a symmetrical bell curve, or
normal distribution, in a set of data
Kurtosis - ANS the sharpness of the peak of a frequency-distribution curve
Variability - ANS The spread or dispersion of scores in a data set. The result of scores
not all being identical
3 types of variability - ANS range, variance, standard deviation
Range - ANS High score minus low score
Range is unstable
