In a frequency distribution, if the class intervals are 0-10, 10-20, 20-30 and their frequencies are 5, 10, 15 respectively, what is the mode?
Correct Answer: 20-30
Step 1: Identify the class intervals and their corresponding frequencies. The intervals are 0-10, 10-20, and 20-30 with frequencies 5, 10, and 15 respectively.
Step 2: Compare the frequencies to find the highest one. The frequencies are 5, 10, and 15.
Step 3: Determine which frequency is the highest. The highest frequency is 15.
Step 4: Identify the class interval that corresponds to the highest frequency. The class interval for the highest frequency (15) is 20-30.
Step 5: Conclude that the modal class is 20-30, as it has the highest frequency.
