Statistics holds a lot of significance in many advanced topics and students would need a strong foundation in statistics to be able to do well in future classes. Today's world is data-driven where statistic applications can be found in abundance in everyday life.
Statistics is the building block for other science and Maths concepts. It allows data to be organised in a way that makes sense for the application of Maths and science formulas.
Statistics also touch on other areas of society such as the government where politicians and campaign managers are able to target specific voter demographics through statistics.
By studying statistics you begin to think like a scientist as it trains your mind to think about data organisation, hypotheses, etc.
You get extremely comfortable around numbers after you gain knowledge in statistics.
Accumulating and interpreting data is not just limited to the field of statistics but other fields like a business also use it to make decisions. Many industries gain invaluable insight by learning how to analyse data since numbers are everywhere and in all types of industries.
Statistics are used for our safety also. For example, one can foresee if a natural calamity might happen in the near future and prepare for it using statistical methods.

FAQs on CBSE Class 10 Maths Worksheet Chapter 14 Statistics - PDF
1. What is the difference between the mean, median, and mode of data
Mean refers to the average of the entire data and if data is x1, x2, ….xn, then mean is calculated as (x1 + x2 + ….. + xn)/n.
The Median is the value that falls in the middle of the data when data is arranged in ascending order. For example, for the data shown below, the median is 6;
2, 3, 4, 5, 6, 7, 8, 9, 10.
If the number of elements is even, then the median is calculated by adding the two numbers in the centre and dividing it by 2. For instance, the median of the following data would be (5 + 6)/2 which is 5.5;
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Mode is the data point that has the highest frequency. If there is more than one data point having the highest frequency, then the data will have more than one mode. Some examples are:
2, 3, 4, 4, 5, 6 - Here the mode is 4 as it is the only number appearing twice.
2, 3, 4, 4, 3, 5, 6 - Here there are two modes, i.e., 3 and 4 as both appear twice in the list.
2. What are the major subdivisions of statistics?
There are mainly two types of statistics as illustrated below:
Descriptive Statistics - The main goal of this subdivision is the reduction of data which means huge amounts of data are summarised in tables and graphs and measuring their variability and calculating measures of central tendencies.
Inferential Statistics -This division uses descriptive statistics for hypothesis testing and drawing conclusions.
3. What is a frequency distribution?
The frequency or number of occurrences of distinct values which are distributed in a given interval or time period. The frequency distribution can be displayed as a table, list, or graphical representation.
