For example, the axes are represented by solid thick lines. A second way to describe a graph is writing an alternate text (alt text). Alternate text conveys the information of a graph such as the title of the graph, the type of graph, the axes, and the trend of the graph which is read aloud by a screen reader.

Describing graphs – the basics
This lesson begins labelling the key features of a graph and naming different graph / chart types. It then provides a practice to see if students can describe a range of different lines (peak, plummet, etc..). This is followed by a fun activity where in pairs students describe and plot the lines on four graphs. Example.
Describing graphs: task
Task: Analyse and evaluate an Office of National Statistics (ONS) graph / chart / table and give a 1-2-minute presentation on your findings.
How do you describe a graph in statistics?
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. A graph with a single peak is called unimodal.

What is a statistic in a paragraph?
Statistics are facts expressed in numbers, based on data from samples and populations. They might be the product of experiments or surveys, and they are meant to be a reasonable subset of a much larger group, so you can draw conclusions about the numbers. But that depends on who has published this statistic.

The type of data often determines what graph is appropriate to use. Qualitative data, quantitative data, and paired data each use different types of graphs.
How to visualize qualitative data?
A Pareto diagram or bar graph is a way to visually represent qualitative data. Data is displayed either horizontally or vertically and allows viewers to compare items, such as amounts, characteristics, times, and frequency. The bars are arranged in order of frequency, so more important categories are emphasized. By looking at all the bars, it is easy to tell at a glance which categories in a set of data dominate the others. Bar graphs can be either single, stacked, or grouped.

A scatterplot displays data that is paired by using a horizontal axis (the x-axis), and a vertical axis (the y-axis). The statistical tools of correlation and regression are then used to show trends on the scatterplot. A scatterplot usually looks like a line or curve moving up or down from left to right along the graph with points "scattered" along the line. The scatterplot helps you uncover more information about any data set, including: 1 The overall trend among variables (You can quickly see if the trend is upward or downward.) 2 Any outliers from the overall trend. 3 The shape of any trend. 4 The strength of any trend.
