The following are a few rules to present the information in the graphical representation:
- Suitable title: The title of the graph should be appropriate that indicates the subject of the presentation.
- Measurement unit: The measurement unit in the graph should be mentioned.
- Proper scale: Choose a proper scale to represent the data accurately.
- Index: For better understanding, index the appropriate colours, shades, lines, and designs in the graphs.
- Create a frequency table, bar graph, pareto chart, pictogram, or a pie chart to represent a data set.
- Identify features of ineffective representations of data.
- Create a histogram, pie chart, or frequency polygon that represents numerical data.
- Create a graph that compares two quantities.
How do you graphically represent mean?
Rules to find the mean graphically In the bar graph we find the heights of the two bars. The average or mean of these heights is found. We then draw a third bar with the average height found in second step. The height of this third bar gives the mean or average of given data set graphically.
Why do we represent data graphically?
Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space.
How do you graphically represent qualitative data?
There are several different graphs that are used for qualitative data. These graphs include bar graphs, Pareto charts, and pie charts. Pie charts and bar graphs are the most common ways of displaying qualitative data. A spreadsheet program like Excel can make both of them.

Quantitative Data Can be displayed through graphs, charts, tables, and maps.
How does graphically represent quantitative data?
Bar graphs, line graphs, and pie charts are useful for displaying categorical data. Continuous data are measured on a scale or continuum (such as weight or test scores). Histograms are useful for displaying continuous data. Bar graphs, line graphs, and histograms have an x- and y-axis.
How do you graph qualitative and quantitative data?
Pie charts and bar graphs are used for qualitative data. Histograms (similar to bar graphs) are used for quantitative data. Line graphs are used for quantitative data. Scatter graphs are used for quantitative data.
How do you show quantitative data graphically?
Quantitative data is often displayed using either a histogram, dot plot, or a stem-and-leaf plot. In a histogram, the interval corresponding to the width of each bar is called a bin. A histogram displays the bin counts as the height of the bars (like a bar chart).
Why do we need graphical analysis?
The graphical analysis creates pictures of the data, and this will helps to understand the patterns and also the correlation between process parameters. Often graphical analysis is the starting point for any problem-solving method.
Why is plotting data important?
Data visualization gives us a clear idea of what the information means by giving it visual context through maps or graphs. This makes the data more natural for the human mind to comprehend and therefore makes it easier to identify trends, patterns, and outliers within large data sets.

What is graph in math?
In Mathematics, a graph is defined as a chart with statistical data, which are represented in the form of curves or lines drawn across the coordinate point plotted on its surface. It helps to study the relationship between two variables where it helps to measure the change in the variable amount with respect to another variable within a given interval of time. It helps to study the series distribution and frequency distribution for a given problem. There are two types of graphs to visually depict the information. They are:

To confirm an applicable scale, vary the axes uniformly and provide the acceptable label on the axes. Finally bear in mind to convey the graph an acceptable title.
Why do pictograms have a key?
Pictograms use the footage to represent information. to form a sense, a pictogram should always have a key. In a pictogram, it's necessary to form a certain image that is the same size, equally spaced out, and lined up one at a lower place the opposite. Example.
Why would temperature graphs be represented using line graphs?
Temperature graphs would sometimes be represented using line graphs as a result of the data being continuous.
What are the three methods of representing data graphically?
The following points highlight the three main techniques and methods used for representing data graphically. The methods are: 1. Histogram 2. Bar Chart 3. Pie Diagrams. Method # 1.

Line Graphs
- A line graph is commonly accustomed to show a trend over a period of days or hours. It is therefore thought of as a series of points that are then joined with straight lines. The ends of the road graph don't need to be a part of the axes. This line graph shows the noontide temperature over an amount of seven days: You can tell that the temperature was at its highest on Monday w…
