5 Kinds of Diagrams in Statistics

Diagram is a description to show or explain a data to be presented. Or other diagram definitions are certain symbols that can be used to describe the means, procedures and activities that are commonly implemented in a system. This time I will share about 5 kinds of diagrams form.

1. Line diagram

Line diagram is a diagram mostly used to present data obtained from time to time on a regular basis with a certain distance. Generally line diagrams are often used to see the progress of something on an ongoing basis.

To draw a line diagram it takes two axes, ie the vertical axis and the flat axis. The flat axis works to show the time, and the axis is upright to show its quantity such as value, quantity, cost, income, and so forth. Next, Draw each coordinate point that shows the observed data at a given time.

Here is an example of a line diagram:

2. Bar diagram

Bar diagram is a diagram that presents data in the form of vertical rectangles or horizontal rectangles. Bar diagram is generally used to describe the development value of a research object within a certain time. The bar diagram shows descriptions with straight or horizontal bars and is the same width with separate trunks.

Here is an example of a bar diagram :

3. Pie diagram

The pie chart is a diagram to describe or represent the data as a circle image. Because of its representation as a circle then the data must form a sum and each datum (data item) can be expressed as a percent (having a certain portion between 0 to 100) against the data.

Here is an example of a pie diagram :

4. Pictogram

The picture diagram or pictogram is a diagram where the data is presented in the form of drawings or paintings to represent objects that display many actual objects. However, the method of data presentation using pictograms has its own weaknesses such as there are pictures of people who only seem half, it is used to represent the number of students who only 10 people.

Here is an example of a pictogram :

5. Histogram

The histogram is a graphical display of the frequency tabulation described in graphical bars as a binary data manifestation. Each rod display shows the proportion of frequencies in each category deet that coexists with non-overlapping intervals.

A histogram is a block beam showing one kind of measurement of a process or event. This graph is very suitable for the data in the grouping. Histogram is a neighboring frequency diagram that looks like a bar chart. The adjacent bar should coincide.

Here is an example of a histogram :
