Hey guys, welcome to this lecture, activity solution performed display descriptive statistics observe that the data for class A and B is stacked. Unlike the previous example, the data is not made available into different columns. Because Minitab requires you to feed the data in a particular format. If the data was made available in different columns, you would have been required to stack it. Do go through our next bonus lecture on Minitab tricks to find out how to easily stack the data using Minitab. Okay, now let's come back to the solution.
Copy and paste this data in Minitab. Choose stat, basic statistics, display descriptive statistics. I repeat to stat basic statistics. Display descriptive statistics. In variables, enter, test score in by variables enter class click statistics. In the display descriptive statistics statistics box, uncheck all the options and keep the following boxes checked.
Only these boxes checked mean standard deviation, median, mode, minimum, maximum and total click OK in each dialog box Here you go, you will find the session window displays one line of descriptive statistics for class A and another line for class B. The sample size in both the classes is 200 each, the mean score for class A is 70.856 and that of class B is 65.485. standard deviation is almost the same, the minimum score for class B has gone below 60. It looks like a few students have failed to score the threshold of 60 marks. Median shows a similar difference as observed in the mean. There are a few students who have scored a distinction that is they have scored beyond 75 in class A, but there are none in class B who have gone beyond the scope. 75 in a nutshell, Class A seems to have marginally outperformed Class B. I have uploaded these activity solution steps as a PDF in the resources section of this lecture.
