Question 5: Find the mean salary of 60 workers of a factory from the following table:
Question 6: Give one example of a situation in which
(i) the mean is an appropriate measure of central tendency.
(ii) the mean is not an appropriate measure of central tendency but the median is an appropriate measure of central tendency.
Measures of Central Tendency
Very often we need to analyse a given data to find a value that can represent the entire data set. In other words we say the central tendency of the data set. Different types of data would require different methods to find this central value which can be used as the representation of the entire data set. For example, average number of students can be find using the mean of the data, splitting apples in large sized and small sized groups would require median and for a shoe company mode will be the best measure to decide about the investment.
So, following are three measures of central tendency that you must understand by watching the video embedded below.
