The modal class of the following frequency distribution will be:
Show Hint
- 1 - 3
- 3 - 5
- 5 - 7
- 7 - 9
The Correct Option is B
Solution and Explanation
Step 1: Identify the class with the highest frequency.
The highest frequency is $8$, which corresponds to the class interval $3 - 5$.
Step 2: Conclusion.
Therefore, the modal class is $3 - 5$.
Top Questions on Statistics
- The company at which Mark is employed has 80 employees, each of whom has a different salary. Mark’s salary of 43,700 is the second-highest salary in the first quartile of the 80 salaries. If the company were to hire 8 new employees at salaries that are less than the lowest of the 80 salaries, what would Mark’s salary be with respect to the quartiles of the 88 salaries at the company, assuming no other changes in the salaries?

- While writing a computer programming code, it was found that Team A incurred 250 errors in a code of 1000 lines while Team B incurred 300 errors in a code of 800 lines. In order to determine whether Team A has performed better than Team B, a statistical hypothesis was set and tested. Then the value of the test statistic is:
