CBSE Notes for Statistics for Economics Chapter 7

There are many situations in our daily life where we know from experience, the direct association between certain variables but we can’t put a certain measure to it. For example, you know that the chances of you going out to watch a newly released movie is directly associated with the number of friends who go with you because the more the merrier!

But there are many other factors too, like your interest in that movie, your budget etc. Thus to analyze the situation in detail, you need to note down your similar past experiences and form a sort of distribution from that data. It is at this point that you require a Correlation Coefficient, which will now provide you with a value, based on which you can calculate the possibility of you not going for the movie this time if your friends don’t turn up! Karl Pearson’s Coefficient of Correlation is one such type of parameter which we’ll be studying in this section. Please refer Statistics for Economics Class 11 Notes Chapter 7 for more information.

The absolute measures of dispersion accurately display the dispersion of data in a given series. However, a drawback to them is that we cannot use them to compare dispersion for series that are in different units. The concept of relative measures of dispersion overcomes this limitation.

When working on a given set of data, it is not possible to remember all the values in that set. But we require inference of the data given to us. This problem is solved by mean median and mode. These, known as measures of central tendency, represent all the values of the data. As a result, they help us to draw an inference and an estimate of all the values. Let us learn about the measures of central tendency and the calculation of Mean Median and Mode. Please refer Statistics for Economics Class 11 Notes Chapter 5 for more information.

NCERT Economics Class 11 books are extremely helpful for the students. Economics is a subject that cannot only be termed as a social science but can also be said to possess the power to explain the working of the economy. From what the economy produces, to what is the rationale behind it, from the standard of living of the country to the history behind it, economics explains it all.
