Extracts from this document...

Introduction

Mustafa Rafik Maths coursework- Memory Josephine believes that there is a difference between visual and aural memory. She uses two tests to investigate her claim. Test 1: Visual memory Josephine gives these 10 pictures cards to Peter. Peter has 10 seconds to look at them. He is asked to recall as many pictures as he can. His result is recorded. Josephine repeats the test with other people. Test 2: Aural memory Josephine reads out the following 10 words to Peter. Peter is then asked to recall as many as words as he can. His result is then recorded. Josephine repeats the test with other people. Introduction We are given a theory, which suggests that there is a difference between visual and aural test. We have to prove that Josephine's theory works, so to do this I am going to ask 20 different people to do the two tests above. I will then try and work out if her theory works by looking at the results that I have obtained by recording the results in a suitable form or way. Aim I have been asked to prove if Josephine's theory works. After asking 20 people I will then try and put my results in a graph or a suitable form in which I can check whether Josephine's theory does work or not. I will then further this investigation by finding out various information such as mode, median, range and mode. ...read more.

Middle

The answer for this is 60% Both visual an Aural test are the same There are two results, which are the same for both visual, and aural so it must be 10% as 2 times five equals to 10. The answer for this is 5% Aural test is better than visual test There are six results, which show that there are better aural test than visual, so this is 30% (6 times 5= 30). The answer for this is 30% This shows that Josephine's theory is correct as there is a difference between aural and visual test, the visual test is much better; this also shows that my prediction was correct as I mentioned that the visual tests would produce better results so I was right. The results also show that the first word is mostly correct in both visual and aural tests, this might be because it is the first picture or word so people remember it more frequently. I will now further my investigation by working out the mode, mean and median. First, I will explain what these types of averages; mode, mean and median are. Mode-: the mode is the number, which occurs most often. Mean-: The mean is sometimes known as the average, it is worked out by doing the following working out, Mean= Sum of a set of values The number of values used Median-: The mode of a particular set of numbers is the middle value when the numbers are put together in order of the size MEAN Now I will work out the mean, which will tell me the average of each of the two tests. ...read more.

Conclusion

3, 4, 4, 5, 6, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 10, 10, 10, I have ended up with two middle numbers so I will have to add these together and divide them by two, as there are two numbers in order for me to get the median. 7+7 = 14 14 divided by 2 = 7 The median for the visual test is 7. Now I will work out the median for the aural test. I will collect all the data, which I obtained in my results. 4 7 5 6 3 5 8 7 6 4 4 3 7 8 7 5 5 3 6 9 The above numbers are my set of numbers for the visual test, so I will now put them in order, from the lowest to the highest. 3+3+3+4+4+4+5+5+5+5+6+6+6+7+7+7+7+8+8+9 Now that I have put the numbers in order, I will work out the middle value by ticking off each number on each side of the above numbers until I am left with one or two numbers which will be the middle number. 3+3+3+4+4+4+5+5+5+5+6+6+6+7+7+7+7+8+8+9 I have ended up with two middle numbers so I will have to add these together and divide them by two, as there are two numbers in order for me to get the median. 6+5 = 11 11 divided by 2 = 5.5 The median for the aural test is 5.5 After finding out the median of both the tests I found out that the visual test had better results then the aural test, this again proves that Josephine's theory is correct as there is a difference between both the aural and visual test. ...read more.
