Algebra 1 Example: Complete the frequency table below.Has an A in math | Doesn't have an A in math | Total | |
Plays an instrument | 20 | 90 | |
Doesn't play an instrument | 20 | ||
Total | 350 |
Using the information in the table, it is possible to determine that the second column contains the numbers 70 and 240. This means that there are 70 students who play an instrument but do not have an A in math and the total number of students who play an instrument is 90. The ratio of the joint frequencies in the first column is 1 to 1 and the ratio in the second column is 7 to 24, indicating a strong positive association between playing an instrument and getting an A in math.
