To find: The mean, median and mode for the provided data set.
The mean and medianare 9.5 and 9.5 respectively.
Given information:
The data set is:
11 |
6 |
9 |
4 |
19 |
10 |
15 |
2 |
Formula used:
Formula to compute the mean and median are:
Median when numbers of observations are evenare:
Concept used:
Mode is a value that happens maximum number of times in a set of data.
Calculation:
The mean is:
To find the Median, data is required in ordered manner. So, the data is arranged in ascending order as follows:
2 |
4 |
6 |
9 |
10 |
11 |
15 |
19 |
Median is computed as:
Here, no value is occurring maximum number of times. So, no modes exist here.
Hence, mean and median and mode are 9.5 and 9.5 respectively.
