Standard Deviation (SD) - ANSWERSThe average amount of variability in a set of scores.
Z-Score - ANSWERSThe number of standard deviations from the mean
Data - ANSWERSA record of observation or an event, such as a test grade or response time
Skewness - ANSWERSThe quality of a distribution that defines the disproportionate frequency in
a set of scores
Data Set - ANSWERSThe collection of data points
Platykurtic Distribution - ANSWERSThe quality of a normal curve that is relatively flat compared
to a normal curve
Descriptive Statistics - ANSWERSValues that organize and describe the characteristics of a
collection of data
Histogram - ANSWERSA graphical illustration that uses different bar heights to show the number
of values that fall within a class interval
Variability - ANSWERSHow much scores differ from one another or the amount of spread or
dispersion in a set of scores
Inferential Statistics - ANSWERSTools used to infer characteristics of a population
,Frequency Distribution - ANSWERSA method that illustrates how often scores occur in a group
called class intervals
Population - ANSWERSAll possible subjects or cases of interest
Unbiased Estimate - ANSWERSA conservative estimates of a population estimate
Exclusive Range - ANSWERSHighest score minus lowest score
Inclusive range - ANSWERSHighest score minus lowest score plus 1
N - ANSWERSRepresents the population size
Leptokurtic - ANSWERSThe quality of a normal curve that is relatively peaked compared to a
normal curve
Mode - ANSWERSThe most frequent occurring score (s) in a set of scores
Median - ANSWERSThe midpoint in a set of values in which 50% falls below and 50% falls above
Mean - ANSWERSThe sum of values divided by the number of values.
Statistics - ANSWERSTools and techniques used to describe, organize, and interpret information
or data
,When do you use the mean ? - ANSWERSWhen scores are not extreme & When scores are not
categorical
What is the most common type of average ? - ANSWERSMean
What are the scales of measurement ? - ANSWERSNominal, Ordinal, Interval, and Ratio
What are averages... measures of central tendency ? - ANSWERSMean, Median, Mode
Which average is sensitive to extreme scores ? - ANSWERSMean
Range - ANSWERSHighest score minus lowest score
Variance - ANSWERSThe standard deviation squared
Kurtosis - ANSWERSThe quality of a distribution that defines how flat or peaked it is
Sample - ANSWERSA smaller set of data or the subset of a population
When do you use the median ? - ANSWERSWhen there are extreme scores.
When do you use the mode ? - ANSWERSWhen the data is categorical and mutually exclusive
(identical)
Average - ANSWERSThe most representative score in a set of scores.
, Frequency Polygon - ANSWERSA graphical illustration that uses continuous lines to show the
number of values that fall within a class interval.

Population Standard Deviations - ANSWERS
Population Mean - ANSWERS
Nominal Level of Measurement - ANSWERSThe numbers in the variables are used only to
classify the data.
Ordinal Level of Measurement - ANSWERSOrdered relationship among the variable's
observations
Interval Level of Measurement - ANSWERSClassifies and orders the measurements, but it also
specifies that the distances between each interval.
Ratio Level of Measurement - ANSWERSCan have a value of zero as well.
Bell-shaped curve - ANSWERSA distribution of scores that is symmetrical about the mean,
median, and mode.
