Probability and Statistics in Grade XI

Previously we have discussed about probability worksheets and Today we are going to study about Probability and Statistics which comes under maharashtra state education board. Probability as the word means the possibility of an outcome. In probability we can say that it means the random possibility that an event or a condition will get fulfilled. Probability is applied in everyday life as well and can be solved using Probability Calculator. There are many day to day activites in our life which are uncertain and are probable in their occurance to solve them we use probability. We can understand it with the help of an example. Let us suppose we are going to toss a coin, a coin has two sides head and a tail. There are two possible outcomes head or tail. The possibility of head is 1/2 and of tail is 1/2 as well.(want to Learn more about Probability ,click here),
We can also understand statistics related to Grade XI .Statistics is basically the study of collection, organization and representation of data with the help of graphs pictures etc. It includes all the aspects of representations like tables, surveys , experiments as well. Statistics is very important part of mathematics of Grade XI. It talks about the analysis of data as well. If suppose we are given an information about the 12 students of grade V and their respective heights. We can show it or represent it in form of a table and show it in form of a bar graph. Bar graph is an example of a statistical representation. The above mentioned information gives a idea about the Probability and statistics of Grade XI. It is also useful in our day to day life.
This is all about the Probability and Statistics and if anyone want to know about Standard distributions then they can refer to Internet and text books for understanding it more precisely.Read more maths topics of different grades such as Rotations  in the next session here.
