What determines the location of a dot on a scatterplot?
A dot is placed on a scatterplot according to its
x - and y -value.
When analyzing a possible relationship for two-variable data, if both variables are
categorical, what is the most appropriate choice to display the data?
a) Side-by-side boxplots
b) Scatterplot
c) Bar chart
d) Two-way frequency table
e) Histogram
Answer: D
A two-way frequency table is the most appropriate way to graphically display a
possible relationship for two-variable data, when both variables are categorical.
A hospital hires an independent consulting firm to perform a study about patients with
high blood pressure, and the medicine they are being prescribed. The study is examining
the relationship between a patient's starting blood pressure when they entered the
treatment program and the dosage of blood pressure medicine they are prescribed during
their treatment. For this study:
What is the explanatory variable? Is the explanatory variable categorical or quantitative?
, What is the response variable? Is it categorical or quantitative?
What graphical display should be used to show the results of the study?
The explanatory variable is patient's starting blood pressure. The explanatory variable is
a quantitative variable.
The response variable is the dosage of blood pressure medicine they are prescribed. The
response variable is also a quantitative variable.
As both the explanatory and response variables are quantitative (Q→Q) , a scatterplot would be
an appropriate graphical display.
When working with two-variable data, if the explanatory variable is categorical and the
response variable is quantitative, what is the most appropriate choice to display the data?
a) Side-by-side boxplots
b) Scatterplot
c) Bar chart
d) Two-way frequency table
e) Histogram
Answer: A
When working with two-variable data, if one variable is categorical and the other is quantitative,
a side-by-side boxplot is the most appropriate way to display the data.
