WGU D582 TEST PAPER QUESTIONS AND
SOLUTIONS 2026 ALREADY PASSED
◍ Scatterplot. Answer: visual relationship between 2 quantitative
variables
◍ Positive Relation. Answer: as x increases, y increases
◍ Negative Relation. Answer: x and y change in opposite direction
◍ 2 relation characterstics between x & y. Answer: Form & Direction
◍ Form. Answer: the shape or pattern data takes in a scatterplot;
linear, curved, or no relation
◍ Linear Relation. Answer: where the overall pattern resembles a
straight line.
◍ Curvilinear Relation. Answer: the pattern of points in a scatterplot
is curved rather than straight.
◍ Direction. Answer: whether the variables change in the same way
at the same time or in opposite ways at the same time
, ◍ Correlation Coefficient. Answer: quantifying the relation
demonstrated in a scatterplot; positive, negative or zero
◍ Stem and Leaf Plot. Answer: analyzing groupings of numbers and
seeing the values in the plot
◍ Central Tendency. Answer: the center of a distribution and is a way
to summarize a large set of numbers using one single score
mean, median, mode
◍ Mean. Answer: "average" of the data set
the sum of the numbers divided by the number of numbers
sum of x / N
preferred when using interval/ratio-level data unless distribution
includes outliers.
◍ μ (mew). Answer: the mean of a population
◍ x̅. Answer: the mean of a sample size
◍ Median. Answer: midpoint of distribution
aka 50th percentile
preferred when using ordinal data and when interval/ratio data
includes outliers.
Arrange the numbers in the set from smallest to largest.
