Hello students steps involved in testing of hypothesis are first one state your research hypothesis as null and alternative hypothesis and next collect data in a way designed to test the hypothesis and the third one perform an appropriate statistical test and next compare the statistical test with the compare the statistic value with critical value and decide and decide whether to accept or reject the null hypothesis and first of if step present the findings in your result and discussion.
01:28
So here first step that is state your research hypothesis here based on the question.
01:39
We have to define the null and alternative hypothesis.
01:42
So alternative hypothesis will be of three types that is right tailed left tailed and two tailed and next collect the data for a statistical test to be valid.
02:02
It is important to perform sampling and collect the data in a way that is designed to test your hypothesis.
02:10
If the data are not representative, then you cannot make statistical inference about the population you are interested in and next perform a statistical test.
02:26
So there are variety of statistical test available variety of statistical tests are available, but based on the question based on the comparison of within group variance, how the spread out the data so versus between group variance or any question anything based in the question.
02:49
We need to select the correct statistical test and next decide whether to reject or accept the null hypothesis.
02:57
We have to calculate the critical value based on the comparison with calculated value.
03:04
If the calculated value is if calculated value is greater than critical value then reject the null hypothesis...
