# I believe that the higher the average hours of TV watched per week decreases the IQ result. Females have a higher IQ and the higher amount of siblings relates to a higher average in TV hours per week.

Extracts from this document...

Introduction

Hypothesis

I believe that the higher the average hours of TV watched per week decreases the IQ result. Females have a higher IQ and the higher amount of siblings relates to a higher average in TV hours per week.

• Investigation.
1. To investigate the range of TV hours watched per week.
2. To investigate the range of IQ.
3. To contrast and compare the relationship between the range of TV hours and IQ.
4. To see if there is a relationship between a higher IQ and genders.
5. To see if there is a relationship between the amount of TV hours watched and the number of siblings.

Specify the Problem and Plan

• Collecting Data
1. Collect data to be used from the spreadsheet already given to us.

Middle

I will print out the sample spreadsheet, including the gridlines and row/column headings to use for my investigation. I will use this data to confirm or disapprove my hypothesis.

Collect, Process and Represent

I have printed out a spreadsheet of my sample.  The data was extracted from the Mayfield high School data produced by Edexcel.  I have taken a stratified sample from years 7, 8, 9, 10 and 11.  I have included the column to help me with my investigation, specifically, Year group, surname, forename, gender, average number of hours of TV watched per week, IQ and the number of siblings. I have sorted them by year group and then by gender in order to compare results more easily.  The spreadsheet is shown on the next page.

Plan.

Conclusion

I will do the same with information of 2. From 3. I will work out percentages from the pie chart.To prove or disprove my hypothesis I will compare the TV hours watched with the IQ making a cumulative frequency graph for each sample and compare the curves. Also, I will show the correlation between this data with a scatter diagram.  To show the relationship of IQ between the genders I will make a bar chart for each gender and year groups, comparing the higher and lower ranges of IQ between the genders. To show the relationship between the number of siblings and average number of hours of TV watched per week I will investigate the correlation in a scatter diagram I will make with the data collected.

and it would be unfair to take the same number of samples from each year group i.e. 5 samples out of 55 is be more than 5 samples out of 200 so stratified sampling will be helpful this is due to the fact the number of student in each year and so there is less chance of unequal representation.
