Explanation of Solution

Given:

The table below shows the scores on a Chem 103 test consisting of 10 questions worth 10 points each.

Student ID	Score	Student ID	Score
1362	50	4315	70
1486	70	4719	70
1721	80	4951	60

4107	40

A frequency table is a table with the frequency of each actual value in the data set.

Approach:

From the given table the number of students with a score of 10 is 1, so the frequency of score 10 is 1, similarly the number of students with a score of 40 is 1, so the frequency of score 40 is 1 similarly frequencies for rest of scores can be computed.

A bar graph is a graph with bars (column) representing each of the actual values in the data set. The height of each column represents the frequency of the value in the data set.

Approach:

From the given table the number of students with a score of 0 is 0, so the frequency of score 0 is 0, similarly the number of students with a score of 10 is 1, so the frequency of score 10 is 1 similarly frequencies for rest of scores can be computed.
