Class 8 ICSE Solutions for Chapter 22 Concise Mathematics - Data Handling

Data Handling

Data handling entails gathering a set of data and presenting it in a new format. The numerical figures that reflect a specific type of information are referred to as data.

Primary Data

Primary data is information gathered by the investigator from firsthand observations with a specific goal or design in mind. Primary data is accurate and timely. Consider the information gathered by a teacher about a student's math performance.

Secondary Data

Secondary data is information that has been gathered for a specific purpose by someone other than the investigator. Government reports, for example.

Raw Data

Data that is merely obtained and put down carelessly, i.e. not in an organized fashion, is referred to as raw data. Computing, analyzing, and understanding this type of data can be challenging.

Arrayed Data

Data that has been classified in a serial or alphabetical sequence, or in an ascending or descending order, is referred to as arrayed data (also known as grouped data). This type of information is simple to compute, analyze, and understand.

Variable

A variable is a quantity that can have several values. Height, weight, and age of children in standard IX, for example.

Representation of Data

In most cases, the data can be represented in one of the following ways. They are as follows:

Bar Graph
Line Graphs
Pictographs
Histograms
Stem and Leaf Plot
Dot Plots
Frequency Distribution
Cumulative Tables and Graphs

Bar Chart

A graph depicting the frequency distribution for nominal or discrete data with a limited number of possible values.
It is made up of a series of bars or rectangles that represent the various possible values.
