Important Topics covered in Chapter 4 - Data Handling

In this chapter, there are various topics related to data handling. Let’s explore some of them.

4.1 Looking for Information - In our daily lives, we encounter data like how many runs a batsman has scored in the last 10 games or how many wickets a bowler has taken. All data collected in all these cases is called data. It is typically gathered in the context of what we are trying to understand. Data can be shown graphically to give you a better idea of what it is. 

The following are the types of graphs explained  in NCERT solution for class 8 maths chapter 4.

• A pictograph representation of data using symbols. 

• A bar graph shows the data by using bars of uniform width, whose height is proportional to their values.

• Double bar graphs display two data sets at the same time. It is useful for comparing data.

• Add information on Pie charts as well.

4.2 Circle Graph or Pie Charts - A circle graph shows the relationship between a whole and its constituents. The entire cycle is divided into segments. The size of every sector is proportional to the activity or data it represents. If we plot the data as a circle, it’s called a pie chart. When we plot percentages or fractions, we use a circle graph or pie chart. 

            4.2.1 Drawing Pie Charts - In pie charts, the appropriate angles need to be calculated in order to represent them in the chart. For example, if a full circle has 360 degrees, the fraction of the 360 degrees for each sector needs to be calculated.

4.3 Chance and Probability - Probability is a number between 0 and 1. Probability means the possibility of something. It is a field of mathematics that deals with the probability of random occurrences. Probability is a concept introduced by mathematics to predict the probability of events. It is simply the probability that a certain event will occur. This is the basic theory of probability. Probability can also be used in probability distribution.

The various kinds of probability factors described in NCERT solution for class 8 maths chapter 4 are:

4.3.1 Getting a result

4.3.2 Equally likely outcomes

4.3.3 Linking chances to probability

4.3.4 Outcomes as events

4.3.5 Chance and probability related to real life
