The table below shows data from a survey about the amount of time high school students spent reading and the amount of time spent watching videos each week (without reading): reading video 5 1 5 4 7 7 7 10 7 12 12 15 12 15 12 18 14 21 15 26 which response best describes outliers in these data sets?

a) neither data set has suspected outliers.
b) the range of data is too small to identify outliers.
c) video has a suspected outlier in the 26-hour value.
d) due to the narrow range of reading compared to video, the video values of 18, 21, and 26 are all possible outliers.

Answer with explanation:

Arranging the data in ascending order

1, 4,5,5,7,7,7,7, 10,12,12,12,12,14,15,15,15,18,21,26

There are 20 data values in data set.

Mean of data set

Since there are , even number of data values in the data set,

So, Median

First Quartile and third Quartile can be calculated directly ,using the concept of even and odd number of Observations in the data set.

Mode> 12

Since data values is negatively skewed, Mean < Median <Mode.

To calculate Outlier

Interquartile Range (IQR)

Also,

No, value exceeds 27, nor any value is less than -5.

So, there are no outliers in Data set, which has 20 values.

Option A:  Neither data set has suspected outliers.

answer: the common difference is -0.10

0.85% : )
