The following are the margins of victory in the matches of a football league :
3, 2, 1, 5, 6, 4, 2, 1, 3, 1, 2, 1, 4, 2, 5, 5, 6, 2, 3, 2
Find the mean of the data.
Given:
The margins of victory in the matches of a football league are:
3, 2, 1, 5, 6, 4, 2, 1, 3, 1, 2, 1, 4, 2, 5, 5, 6, 2, 3, 2
To do:
We have to find the mean of the given data.
Solution:
We know that,
Mean of a given data $=$ Sum of observations $\div$ Total number of observations
Sum of the observations$=3+2+ 1+ 5+ 6+ 4+ 2+ 1+ 3+ 1+ 2+ 1+ 4+ 2+ 5+ 5+ 6+ 2+ 3+ 2=60$
Mean of the given data $=\frac{60}{20}=3$.
The mean of the given data is 3.
