Now, we can rewrite the data set as a list of numerical values.
0, 0, 1, 1, 1, 1, 2, 2, 4, 5
Mean
The mean of a data set is the sum of the values divided by the total number of values in the set. Let's start by calculating the sum of the given values.
0+0+1+1+1+1+2+2+4+5
= 17
There are 10 values in our set, so we have to divide the sum by 10.
Mean: 17/10=1.7
Median
When the data are arranged in numerical order, the median is the middle value — or the mean of the two middle values — in a set of data. The data set has been already ordered, so we can find the median.
0, 0, 1, 1, 1, | 1, 2, 2, 4, 5
Since there are 10 values, there is no one middle value. Therefore, for this exercise, the median is the mean of the two middle values.
Median: 1+ 1/2=1
Mode
The mode is the value or values that appear most often in a set of data.
Let's find the mode of the given values.
0, 0, 1, 1, 1, 1, 2, 2, 4, 5
The value that appears most often is 1.
Mode: 1
