Question

The data below are the number of cattle on farms in the United States (in millions) for each year that begins a decade from 1910 to 2010. Draw a box plot for the data below. Are there any outliers? If so, what are they? 58.0, 71.4, 64.9, 70.0, 74.5, 98.9, 114.4, 112.3, 95.4, 99.8, 91.9.

Answer 1

Box Plot of no of cattles in US Cattles

Now from given boxplot:

There is no any outlier detected in the boxplot here min point is 58 and max is 144.4 its not far from each other all points are distributed in these interval. if the points are outside of  upper or lower line of box plot then the outlier will be detected but here all points are in the line.

Here in boxplot Black circle is median and cross circle is mean.

this is the left skewd boxplot.

The descriptive statistics is:

Min = 58

Max = 144.4

Quartile 1(Q1) = 70

Median (Q2) = 91.9

Q3 = 99.8
