Please show me the steps please Below are the boxplot and pp

Below are the boxplot and pplot for a dataset Based on these graphs describe the shape of the data. Based your answer in part (a) which would be the most appropriate measures of center and dispersion for this dateset

Solution

Ok, consider the shape of the graphics to draw some conclusions.

First in the boxplot we can see that the data are biased to the left, as we left boxplot tail is longer than the right. That means that data are more concentrated in the range of 66 to 70 (students heights).

Also, the median is 68. vertical center line provides us with that data.

The box is not symmetric about the axis of the median, indicating that this medium does not match the average or with fashion.

The graph of probabilities, we can see that the spread of the data from the mean is wide, suggesting that we would obtain a variance, and hence a very high standard deviation values.

B)

The most appropriate measures of central and dispersion data for this set are the median and standard deviation respectively. These are the ones that show more precise about the behavior of the current dataset values.
