Step 1
Boxplot :
A boxplot is a graphical method that is used to visualize the distribution of data based on five number summary values.
Cumulative histogram:
A cumulative histogram is a graphical method that is used to visualize the sum of frequency of bins of the smaller values of the response variable.
Histograms:
Histogram is a graphical representation to display continuous data. In histogram, there is no gap widths between each bar. Each bar in histogram represents the frequency of occurrences in the corresponding interval.
Mean:
It is a summary value which provides the average value of a numerical variable.
