What is the median of the data set: 12, 15, 18, 20, 25?

If the mode of the data set 5, 7, 7, 9, 10, 7, 12 is?

Mean of the numbers 8, 12, 15, 10, 5 is:

The sum of the frequencies of a frequency distribution is:

Which of the following is NOT a measure of central tendency?

If the mean of 5 numbers is 20 and one number is 30, what is the mean of the remaining 4 numbers?

In a frequency distribution, the modal class is the class:

Find the median of the following data: 5, 8, 12, 15, 18, 20, 22, 25, 30, 35.

The mean of 10 observations is 50. If two observations 40 and 60 are removed, the mean of remaining observations is:

Given the grouped data: Class intervals: 0-10, 10-20, 20-30, 30-40 Frequencies: 5, 8, 12, 5 Find the modal class.
