Is 11.5 out of 20 a good grade in a biology exam?

It depends on the grading scale of the exam. In general, 11.5 out of 20 would be considered slightly below average. It's important to review what areas you struggled in and work on improving them for the next exam.

What is a two-way table used for?

People use Two-Way Tables to examine the relationship between two categorical variables. Example Question Megan has collected information from people in her year group about which science people prefer. Complete the two-way table to show her information. Biology Chemistry Physics Total Girls 20 15 50 (20 for Biology, 15 for Chemistry and 50 is the total) Boys Total 40 33 100 ( 40 for Biology, 33 for Chemistry and 100 is the total) First, we can work out how many boys were asked in the survey. To do this, we take the number of people asked (100) away from the number of Girls asked (50). 100-50 = 50. 50 boys were asked in the survey. We can work out that 27 people like Physics because 40 + 33 = 73 100 - 27 =73. From there we can see that 12 boys like physics since 15 girls like Physics. 15 + 12 = 27. Next, we can see that 20 boys like Biology since 20 girls like Biology and 20 + 20 = 40. To work out how many girls like Biology, we add up the total of girls that preferred Biology (20) and the total of Girls that like Physics (15), add them together and work out what we need to add to the total (35) to make the total of 50. In this case, it's 15. So 15 girls like Chemistry. We can see that 18 Boys like Chemistry since 33 - 15 = 18. So this is what your completed Two-Way table should look like: Biology Chemistry Physics Total Girls 20 15 15 50 Boys 20 18 12 50 Total 40 33 27 100 You will then be asked questions from this table like: ' How many Girls were in the survey?' (50) ' How many Girls prefer Biology?' (20) ' What is the difference between the total of Boys who prefer Chemistry and the number of Boys who prefer Physics?'(6)
