The mean is
Explanation of Solution
Given:
The point scored by a football team are:
Concept used:
Arithmetic mean:
Mean:
Median
Mode= the value in the data set that occurs most frequently.
Calculation:
According to the given:
The point scored by a football team are:
Mean is the average of the data:
The mean
Median is calculated by making the order in increasing order and then choose the middle value.
If the number of the data is even then there will have two middle value so, by taking the mean of two middle value get the median as:
The data in increasing order is:
Total number of data is
The median is
Mode is the value that occurs maximum or most often.
Taking the increasing order of the data:
Her the maximum value that occur is
The mode is
Range is the difference between largest and smallest value.
Taking the increasing order of the data:
Here largest value is
The range here is
Hence, the mean is
