Numbers in statistics incorporate data visualization as an integral part of Mathematics. The summary of the dataset can be understood by a visual data plan in Maths. The main goal of statistics is to present the data in a meaningful way along with values. The graphs can help in conveying the information to the users easily.
Be it Maths or Economics, qualitative, quantitative and paired data in the graphs can be demonstrated and illustrates. Now, you may want to know what are the types of graphs in maths and statistics? But before going into depth, try to know what a graph is?
What is Graph?
The graph is a pictorial representation of organized data planned with data points. Some students lack ideas about statistics and graph. For them knowing about it is important.
Have you ever heard? “A picture says a thousand words.” The graph says a lot in a pictorial form. It says a million stories by showing the relation between two or more things.
Each stroke, point, shape, and colour in the graph has different meanings. Their structures, lines, and points also vary with each other. Most of the economic statistics, global condition, and various other things are described with a graph. You may acquire information about various types of graphs and their uses.
1. Line Graph
This graph or chart graphically displays the changes that occur with time. Every line graph has specific points that connect the data and show a trend in continuous change. A line graph has both the x-axis and y-axis. The time of the graph is displayed on the horizontal axis. Take a look at the uses of line graphs:
- You can show trends with the help of line graphs.
- You may make predictions that are based on history over time
- Price inflation can be shown with the help of a line graph.
- You can compare two or more situations, variables, and information with the given period with the help of line graphs.
2. Bar Graph
The bar graph is also known as the Pareto diagram that visually represents the qualitative data. The data is displayed with vertical and horizontal charts. The viewers can compare the frequency, time, characteristics, and amount. The bars are developed with the economic decision-making plotting graph and data. Have a look at some uses of bar graphs:
- You can show the disparity between rich and poor in the bar diagram.
- The geographic parts of the world along with the temperature are demonstrated in the bar graph.
The histogram is another type of graph. This graph is always used for quantitative data with the range of value that is listed down with frequency bars. The histogram also looks like a bar graph. The measurement of frequency bar is measured with various types of arrangements with quantified base. Various variables and opinions are managed with the graph. Have a look at some uses of the histogram graph:
- Data symmetry is followed with the histogram graph
- Spotting deviations are maintained with equal distribution
4. Time Series Graphs
The time-series graph displays the data at various points in time. The name implies the graphs measured over the trends of the time. The timeframe is managed with all the axis over time. Both the X-axis and Y-axis are connected with the series of the time along with the graphs. Have a look at some use of time series graphs:
- The date and time are managed with time series graphs
- Plot measurement is managed with the categorical data displayed with a dashed line.
5. Pie Chart/Graph
The pie chart is also known as a circular graph that illustrates the numerical proportions of the dataset. You may find the division of the graph planning in a particular numerical element with several sets. Each sector of the pie chart represents the proportion of the element along with the dataset.
You can divide the proportion by the percentage area concerning the area of a circle. Have a look at some uses of the pie chart. Take a short glimpse at the uses of the pie chart:
- Pie chart summarizes the data with visual appealing form
- The comparison is quite simple with various graph types.
6. Dot Graph or Plot
The dot graph and plot are vertically represented in the histogram and bar chart. The height and the aggregation of the dot-like markers are managed with the frequency of the elements. The particular class interval is also planned with various types of interval period along with the plot plan. Take a look at some uses of dot graph:
- Dot graphs are managed with the slop planning of data accuracy
- The dimension of the scatter plots are managed with the lines are planned with plotting works
After going through the graphs and the chart description, you may have understood what are the types of graphs in maths and statistics? With the help of the planning of graph dimension, you can use effective methods of graphical representation. Book a free trial session to get the graphs and the statistics class.
