Concept explainers
(a)
To describe:
The number of songs downloaded by group of freshmen to the number of songs downloaded by sophomores in a given data.
(a)
Explanation of Solution
Given:
Survey size
First quartile
Third quartile
Concept used:
Bivariate joint frequency distribution are contingency table.
The total row and total column of the marginal distribution while the body of the table is the joint frequencies
Calculation:
Draw the graph
Both distribution are skewed left
The centers and spreads of the two data sets are close to each other
The median for sophomore is
Both data sets have more variability.
(b)
To describe:
The median greater than the mean for group of freshmen in a given data.
(b)
Explanation of Solution
Given:
Survey size
First quartile
Third quartile
Concept used:
Bivariate joint frequency distribution are contingency table.
The total row and total column of the marginal distribution while the body of the table is the joint frequencies
Calculation:
Draw the graph
Both distribution are skewed left
The centers and spreads of the two data sets are close to each other
The median for sophomore is
Both data sets have more variability.
This mean that most of the data are on the right by box and whisker plot.
