Answer:
To determine the Mean, Median and Mode of a frequency distribution table, we will first sort the data from smallest variable (age) value to highest first.
Then we will add additional cumulative frequency table to the data set.
The mode is easy to find as it is the value associated with greatest frequency
Mode: In the given data, mode is 32 (greatest frequency = 17)
Median: Since median is the middle value, in the given data the position of the middle number is
= (n+1)/2 = (209+1)/2 = 105, the value corresponding to position 105 is 29.
