O DATA ANALYSIS AND STATISTICSFinding the mode and range of a data setEach day, Susan records the number of news articles she reads. Here are her results for the last eight days.3, 6, 6, 9, 1, 6, 9,6Find the range and the mode for the data.

Sagot :

We are given the following data set:

[tex]3,6,6,9,1,6,9,6[/tex]

We are asked to determine the range. To do that we will arrange the data from smallest to greatest values, like this:

[tex]1,3,6,6,6,6,9,9[/tex]

Now, the range is the difference between the smallest and greatest value, therefore:

[tex]\text{Rage}=9-1=8[/tex]

Therefore, the range is 8

Now, the mode is the value that repeats the most. In this case, we have that the value "6" is repeated 4 times, therefore, the mode is:

[tex]\mod e=6[/tex]
