Question

The picture is an example of__________.

A. Data analysis
B. Statistics
C. Mensuration
D. Data handling

Answer 1

Hint: Here we have to identify the given picture. Also, we have to choose a correct option from the given options by using the properties. It is a bar diagram that represents the set of values.

Formula used: Some of the properties of the bar diagram is
All the bars have equal width.
The heights of all the bars indicated the frequency which means that the frequency is plotted on the y axis.
All bars are equally situated from each other.

Complete step by step solution:
Here, the given picture is of a bar diagram. The x axis represents the variables that are the number of sites here. The y axis is the frequency. The height of each bar represents the frequency.
According to the options,
Option A is Data analysis. Data analysis means to study the data obtained and analyse it. It is done to obtain conclusions from the data.
Option b is Statistics. Statistics is a subject that comprises many branches. The picture is undoubtedly part of a branch or subpart of statistics but it is not the entire subject.
Option C is Mensuration. Mensuration is the part of geometry. It is concerned with lengths, areas and volumes.
Option D is data handling, Data handling means to organize the raw data in a representable way so that the data can be easily represented for further studies.

Hence, the correct option is B.

Note: A bar diagram is used to represent the data in a graphical way so that the data can be easily interpreted. The advantages of using a bar diagram is, it is easy to understand. It summarizes a large data set in a visual form. It helps to estimate the key values at a glance.
