How do you explain a box plot?

How do you explain a box plot?

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median.

How do you describe a Boxplot distribution?

The box plot shape will show if a statistical data set is normally distributed or skewed. When the median is in the middle of the box, and the whiskers are about the same on both sides of the box, then the distribution is symmetric.

How do you describe a Boxplot in an essay?

Box Plots and How to Read Them The box ranges from Q1 (the first quartile) to Q3 (the third quartile) of the distribution and the range represents the IQR (interquartile range). The median is indicated by a line across the box. The “whiskers” on box plots extend from Q1 and Q3 to the most extreme data points.

How do you read a box plot graph?

At the ends of the box, you” find the first quartile (the 25% mark) and the third quartile (the 75% mark). The far left of the chart (at the end of the left “whisker”) is the minimum (the smallest number in the set) and the far right is the maximum (the largest number in the set).

How do you describe data in a graph?

Bar graphs divide the data into separate bars and lets you track progress over time. To describe the graph, follow the trend from left to right and describe if it does down, up, or stays the same.

Does a box plot show the mean?

A boxplot, also called a box and whisker plot, is a way to show the spread and centers of a data set. Measures of center include the mean or average and median (the middle of a data set). The box and whiskers chart shows you how your data is spread out.

What is the shape of a box plot?

In its simplest form, the boxplot presents five sample statistics – the minimum, the lower quartile, the median, the upper quartile and the maximum – in a visual display. The box of the plot is a rectangle which encloses the middle half of the sample, with an end at each quartile.

How do you describe the shape center and spread?

The center is the median and/or mean of the data. The spread is the range of the data. And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform.

How do you start an explanation for a graph?

The caption on a graph, table, chart or image should describe the kind of information displayed in the graph so that readers immediately understand the information being presented to them. The key gives important information about the data in the graph and helps readers to understand the data.
