What are measures of central tendency?

Mean, median and mode are common measures used to describe the central or typical value of a data set.

How do I find the mean of grouped data?

Multiply each value or class mark by its frequency, add the products and divide by the total frequency.

Organise the frequency table carefully and check totals before applying the selected formula.
