How do outliers affect data analysis? A.They may significantly affect the mean of the data. B.Not enough information. I would need to know what the data points are. C.They afect the mode of the data. D.They do not, just calculate them with the data the same as all the other data. PLEASE HELPPP!!!!!!

Answer:

A.They may significantly affect the mean of the data.

Step-by-step explanation:

The outliers may significantly affect the mean of the data.

What is outlier?

The extreme values in the data are called outliers.  

Example: For a data set containing  2, 19, 25, 32, 36, 38, 31, 42, 57, 45, and 84.

In the above number line, we can observe the numbers 2 and 84 are at the extremes and are thus the outliers.

The outliers are a part of the group but are far away from the other members of the group.

For example:

Consider the data:  70, 73, 77, 71, 7, 73, 72, and 78

Let's calculate the mean to understand how the outlier affects the results.

Here, the datapoint 7, is an outlier.

Mean (with outlier)

=70+73+77+71+7+73+72+78/8

=521/8

=65.1

Mean (without an outlier)  = 70+73+77+71+73+72+78/7 = 514/ 7 =73.4.

the outlier creates a variation in the mean value of the data.

As, from the example discussed above we have seen that outliers depends on mean of the data.

Hence, outliers may significantly affect the mean of the data.
