5 Graphs Commonly Used in Statistics

In mathematics and statistics, several types of graphs are used to display data visually. The most typical and frequently used charts or graphs are described here.

Chart and Graph Types

The following is a list of the most popular types of graphs:

  • Trigonometric graphs
  • Exponential graphs
  • Logarithmic graphs
  • Statistical graphs
  • Graph of Frequency Distribution

Graphs with statistics

The graphical depiction of statistical data in a visual format is known as a statistical graph or chart. To make it simpler to comprehend and analyze statistical data, a set of data is represented by statistical graphs. The following list includes the many graph types often used in statistics.

Types of Statistics Graphs

There are four primary kinds of graphs in statistics, including bar charts, line charts, histograms, and pie charts. What follows is a brief clarification of those concepts.

🟢 Bar Diagram

Bar graphs are a visual representation of grouped data in which the length of the bars is inversely related to the measure of the data. The chart’s vertical axis specifies discrete data, while the horizontal axis shows categorical data.

🟢 Line Diagram

A line graph is a type of graph that uses points and lines to show change over time. The figure shows quantitative data between two changing variables by connecting a succession of subsequent data points with a straight line or curve. On a vertical and horizontal axis, linear charts contrast these two variables.

🟢 Histogram

A histogram graphic using linked rectangular bars shows the frequency of discrete and continuous values in a collection. The number of observations in this example that fit within a particular class interval is shown by a rectangular bar.

🟢 Inflationary Graphs

Exponential graphs illustrate exponential functions by displaying the points on graph paper using a table of values. Depending on the function, exponential charts may have a graph that is either a rising or decreasing type of curve. The example that follows will make it easier to comprehend the idea of charting exponential functions.

🟢 Graphs of the logarithm

The approaches for graphing exponential and logarithmic functions are similar since they are the opposite of each other. The graph of any formula will be the inverse of that of an exponential.

Graphs using trigonometry

To understand the graphs of each function in detail, along with their maximum and lowest values and solved examples, see trigonometry graphs.

Graph of Frequency Distribution

A relative frequency graph shows how often each outcome occurred in a given sample. The results are in one column and the frequency (i.e., the number of times they occur) is in the other column.

There are two types of frequency graphs that are frequently used:

  • Polygon of frequency
  • Graphs of cumulative frequency distribution
