RD Sharma Solutions For Class 8 Math

In the recent past, the term ‘Statistics’ in the high school curriculum has been replaced by Data handling. 

 

Data handling can be considered as an updated form of statistics that can provide a learning base where data can be gathered, analyzed and in fact totally explored. Data is some numerical observations collected by the students and handling involves analyzing and recording them in such a way that it becomes meaningful to others. In a simple way it can be explained with an example. Any collected information about the runs scored by a batsman in the last 5 ODI matches, the number of wickets taken by a bowler in the last 5 tests, the marks earned by your class in the Science unit test, or the number of novels read by each of your friends in your daily life is referred to as Data. 

 

Now to record the data in a systematic way, and then analyze the results is what we mean by Data handling. So, Data Handling is the process of collecting, recording and displaying information in such a way that it is useful to others. Data is sometimes graphically represented to give a clear picture of what it represents. Data can be represented in various forms like by a Pictograph, line graph, a bar graph, dot plots, frequency distribution, a Double Bar Graph, or by Histogram.

 

Data handling is one of the important chapters for Class 8 students as it tests one's logical thinking, critical thinking skills, and presentation skills. In future, it will also help them to understand issues related to security, confidentiality and preservation of their research data.

4. What are the common misconceptions seen among class 8 students about data handling?

In many times the students collect data without serving any real purpose. Data collection is much beyond simply collecting values, projecting them on a whiteboard, and lecturing a group of people. It is a panoramic subject dealing with analysis, predictions, business, forecasts, and many more scientific and social parameters. Class 8 students often think that if they produce graphs or neatly drawn charts or pictographs they can fetch good marks but that is not the case. They need proper interpretation of their graphs and charts without which their data handling will be of no use.  They should always keep in mind that data handling is not mere collection or drawing. The most important part of data handling is analyzing and interpreting results.

5. What are the methods of data collection?

The methods of data collection are Surveys, experiments, and simulations. Surveys serve as the starting point for pupils to gather their own data, represent and analyze the data gathered. Experiments require more data gathering than surveys since they use both test and control subjects. Simulations resemble experiments but are of more significance since they use random number devices to model real-world situations.  Proper methods of data handling mean a more scientific approach that can help in taking proper decisions.
