Hello students,Previously we have discussed about how to do trigonometry step by step and today we are going to discuss the statistical methods to make inferences which comes under 12 gujarat board syllabus. As we know that statistics is concept by which we organize our data and display that data and this process includes complete process of the data analysis and this process starts from inspecting data to modeling data, it also covers cleaning data as well as transforming data.
Statistical methods to make inferences is a process, that uses the organized information so that it can obtain and make a final decision or conclusion and all the process is done when our system get affected by random variation and due to this some type of datasets is arises and conclusion made from obtained datasets. Statistical inferences are also known as the statistical induction and inferential statistics. Sometimes the result or final outcome of Statistical inferences can be a answer for the next questions.
Methods of statistics are also the basis of statistics type mathematics. They provide the primary research papers, various types of proofs and theorems so that we can complete our research. Descriptive and probability distribution are also assumes the methods of statistics. Lets take an example that will show the use of statistical inferences.
Example: - A card is taken from a shuffled pack of cards and the total trails are 300.
Suit Spades Clubs Hearts Diamond
No. of times drawn 70 50 100 80
Solution: - Find the probability of To got Hearts cards and Except Diamond card
-Total number of events = 300
Number of trial of hearts cards = 100
P (drawn card is heart)
100/300 = 0.33
-Total number of events except diamond card is 70 + 50 + 100 = 220
P(the card is not diamond)
220/300 = 0.73
In the next session we will discuss about free online math tutoring and You can visit our website for getting information about physics homework help.
