a. What is the mean number of bikes per day? [already answered]
b. Identify two outliers for the data. Describe how the outliers affect the mean.


"the numbers, Mason, what do they mean??"


Sagot :

The mean number is 8.7 and the outliers 1 and 2 reduce the mean value

How to determine the mean number?

The dataset is given as:

10, 12, 8, 11, 13, 9, 2, 1, 9, and 12​.

The mean number is calculated using:

Mean = Sum/Count

So, we have:

Mean = (10+ 12+ 8+ 11+ 13+ 9+ 2+ 1+ 9+12​)/10

Evaluate

Mean = 8.7

Hence, the mean number is 8.7

The outlier and how it affects the mean

Outliers are relatively far from other data elements of the dataset

In the given dataset, 1 and 2 are far from other data element.

So, the outliers are 1 and 2

Because 1 and 2 smaller than other data elements, they affect the mean by reducing the mean value
