▶ A linear relationship exists between the two variables
No relationship exists between the two variables
A nonlinear relationship exists between the two variables . Answer: A
scatter plot is a simple, yet useful, graphical tool. We plot each pairing: (x1,
y1), (x2, y2), and so on. Once the data are plotted, according to the
textbook, the graph may reveal which of the following? (Select all that

Multiple select question.
A linear relationship exists between the two variables
No relationship exists between the two variables
A bar chart would have been a better choice
A nonlinear relationship exists between the two variables
▶ Measures of association . Answer: Which numerical descriptive measure
shows whether two numerical variables have a linear relationship?
Multiple choice question.
Measures of dispersion
Measures of central location
Measures of shape
Measures of association
▶ central . Answer: The term ______ location relates to the way numerical
data tend to cluster around some middle or central value.
▶ μ, where μ is the Greek letter mu . Answer: The only thing that differs
between a population mean and a sample mean is the notation. The
population mean is referred to as:
Multiple choice question.
There are many differences
the number of observations in a population
x (pronounced x-bar)
μ, where μ is the Greek letter mu
▶ true . Answer: True or false: After arranging the data in ascending order
(smallest to largest), we calculate the median as (1) the middle value if the
, number of observations is odd or (2) the average of the two middle values if
the number of observations is even.
▶ Show the most-or least-frequently downloaded music genres across
various music streaming platforms
Show the inventory items which need to be replenished, which items have
plenty on hand inventory, and which items should be evaluated to order
Show which products are the best-or worst-selling products at various
stores . Answer: There are a number of ways to display a heat map, but
they all share one thing in common—they use color to communicate the
relationships between the variables that would be harder to understand by
simply inspecting the raw data. Choose all the examples below that would
be a good usage for a heat map.
Multiple select question.
Show the most-or least-frequently downloaded music genres across

▶ Measures of dispersion . Answer: We can use numerical descriptive
measures to extract meaningful information from data. Which measure
gauges the underlying variability of the data?
Multiple choice question.
Measures of shape
Measures of central location
Measures of association
