Question

Mean, Median and ModeThe data set below provides the number of children for each of the 12 adults in a survey.3,2,1,1,2,2,0,1,1, 4,0,2

Answer 1

1) Considering these data points, let's rewrite them orderly:

0,0,1,1,1,1,2,2,2,2,3,4

2) The Mean is found by adding all of them and dividing them by the number of Data Points:

`\bar{x}=(0+0+1+1+1+1+2+2+2+2+3+4)/(12)=(19)/(12)=1.58`

2.2) Since we have 12 data points then the Median will be the average between the 6th and the 7th data point:

`Md=(1+2)/(2)=(3)/(2)=1.5`

Note that the 6th data point is the number 1, and the 7th is the number 2.

2.3) The Mode is/are the most repeated data point in this data set. So examining that we can write the following:

`Mo=1,2`

Note that we have here a bimodal data set for we hav
