Question 1: The following number of goals were scored by a team in a series of 10 matches: 2, 3, 4, 5, 0, 1, 3, 3, 4, 3
Find the mean, median and mode of these scores.
Question 2: In a mathematics test given to 15 students, the following marks (out of 100) are recorded:
41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60
Find the mean, median and mode of this data.
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.
- Mean
- Median
- Mode
