Prediction
I predict that the visual test will produce better positive results, as it is easier to remember things while looking at them rather than hearing them from somebody else and then trying to remember them.
Results
I will now show my results by showing which words they got right by putting a star (*) near each word the person got correct.
Aural test
Person 1-10 = Male
Person 11-20 = Female
Visual test
Person 1-10 = Male
Person 11-20 = Female
Now I will show my results in a table form showing the results of each person in number form.
Out of 10
From the above results i asked 10 people which were male (person 1 to person 10, and 10 people who were female (person 11 to person 20).
I also asked a particular age range, which in my case were fifteen to sixteen years old. I did this to make sure that the results were fair in order for me to prove Josephine’s theory works. I also did this as age determines how good there and bad there memory is, as old peoples memory is usually not as good as young peoples memory so that’s why i only asked a young age to make it fair.
I will now find the percentage of which test have better results.
Visual higher than aural
There are 12 results showing that the visual test has better results than the aural test therefore the percentage of this must be 5 times 12 equals to 60% as each 1 is worth 5% (100/20=5)
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.
Now that I have put the obtained all the numbers I need to work out the man, I will work out the mean number by adding all the numbers together and then dividing by the amount the amount of numbers I added together.
3+4+4+5+6+6+6+6+7+7+7+7+8+8+8+8+8+10+10+10 = 138
After adding all the numbers I got an answer of 138, I will now divide this by 20 as I added 20 numbers to get this figure, after dividing by 20 I will get the mean of the visual test.
138 divided by 20 = 6.9
The mean for the visual test is 6.9
Now I will work out the mean of the aural test and then compare both of the tests and see which one has a higher mean3+3+3+4+4+4+5+5+5+5+6+6+6+7+7+7+7+8+8+9 = 107.
Now that I have put the obtained all the numbers I need to work out the man, I will work out the mean number by adding all the numbers together and then dividing by the amount the amount of numbers I added together.
3+3+3+4+4+4+5+5+5+5+6+6+6+7+7+7+7+8+8+9 = 107
After adding all the numbers I got an answer of 107, I will now divide this by 20 as I added 20 numbers to get this figure, after dividing by 20 I will get the mean of the aural test.
107 divided by 20 = 5.35
The mean for the aural test = 5.35
This tells that the mean (average) for the aural test is lower than the visual test as the visual test result was 6.9 whereas the result for the aural test was 5.35, indicating that peoples visual is much better than their aural and they can remember things much easily by looking at them than by listening to them. This also proves to me that again Josephine's theory was right as there is difference between the visual test and the aural test, this also tells me that my prediction was also right as i said that the visual test will produce much more positive results than the aural test.
MODE
I will now work out the mode of the visual test and then the aural test.
Visual test
First, I will obtain all the numbers that I got in my results for the visual test.
Now i will collect all the data and show how many times each number appears.
Number 3 appears 1 time
Number 4 appears 2 times
Number 5 appears 1 time
Number 6 appears 4 times
Number 7 appears 4 times
Number 8 appears 5 times
Number 10 appears 3 times
Now that i have showed how many times each number appears, i will now find out which number appears the most,
The number, which appears the most, is eight, as it appears 5 times and it more than any other number.
Now I will find out the mode for the aural test so I can compare the two results and see which test produces more results that are positive.
Now I will collect all the data and show how many times each number appears.
Number 3 appears 3 times
Number 4 appears 3 times
Number 5 appears 4 times
Number 6 appears 3 times
Number 7 appears 4 times
Number 8 appears 2 times
Number 9 appears one time
Now that I have showed how many times each number appears, I will now find out which number appears the most,
The number, which appears the most, is seven and five, as it they both appear 4 times and it is more than any other number.
This tells me that again the visual test has produced a better outcome as it has a higher mode than the aural test. This again proves that Josephine’s theory works, as there is a difference between the two tests.
MEDIAN
Now I will work out the median of both the tests, which will tell me the middle number of both the tests.
First, I will find the median of the visual test. I will collect all the data, which I obtained in my results.
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, 4, 4, 5, 6, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 10, 10, 10,
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, 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.
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.
