When analysing bar charts and trend graphs it is good practice to describe what the graph is measuring. If there is no title you should give a description of what the two axes (i.e. the horizontal line and the vertical line) are representing.

11 Ιουν 2021 · Y-axis representing counts, variable function (average, sum, standard deviation), or other summary value. Categories or discrete values on the x-axis. Vertical bars representing the value for each category. Optionally, the bars can be clustered in groups and/or stacked to facilitate comparisons.

A bar graph is made up of bars - columns - plotted on a chart. Here is how to read a bar graph. The bars represent discrete data. The height of each bar indicates the value of that bar as defined by the y-axis Axis Label.
We consider three uses of graphics in statistical analysis: Displays of raw data, often called “exploratory analysis.” These don’t have to look pretty; the goal is to see things you did not expect or even know to look for.
INTRODUCTION TO STATISTICAL ANALYSIS. LEARNING OBJECTIVES: After studying this chapter, a student should understand: notation used in statistics; how to represent variables in a mathematical form for statistical purposes; how to construct frequency distributions, histograms, and bar graphs;
