Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question
Describe what the graph reveals about the association between these two variables for the 1200 College students in the sample.

Transcribed Image Text:A random sample of 1200 U.S. college students was asked, "What is your perception of your own body? Do you feel that
you are overweight, underweight, or about right?" The two-way table summarizes the data on perceived body image by
gender. The segmented bar graph displays the distribution of perceived body image by gender.

Describe what the graph reveals about the association between these two variables for the 1200 college students in the
sample.
O The graph does not reveal an association because the percent of students who responded, "about right" seems fairly
similar between the males and females.
O There is an association between perceived body image and gender because knowing which gender a college student

Describe what the graph reveals about the association between these two variables for the 1200 college students in the
sample.
O The graph does not reveal an association because the percent of students who responded, "about right" seems fairly
similar between the males and females.
There is an association between perceived body image and gender because knowing which gender a college student
is will help us predict what their response was about their perceived body image.
The graph does not reveal an association because the smallest percentage of both genders responded "underweight."
O The graph reveals an association because there were students from both genders who answered "underweight,"
"overweight," and "about right."
There is an association between gender and perceived body image for students in the sample because the segmented
bar graph shows that the distribution of responses for students from both genders add to 100%.
