Aim - To find any relationships between IQ and key stage 2 results.

Hypotheses

1) Students with a high IQ will achieve high mark in their key stage 2 results.

2) Students with a low IQ will achieve a low mark in the key stage 2 results

3) Girls will achieve an overall better result than boys in the key stage 2 result.

4) Girls will on average have a higher IQ level than the boys.

The Data

I will need 40 students to compare and examine in my investigation. To get these students I will randomly choose 20 boys and 20 girls. I have chosen 20 students from each gender because it makes the investigation fairer. I have chosen 40 students overall because it gives a wide range of results to analyse. To record the data I hope to use different tables, charts and graphs. I will use these charts and tables to draw conclusions and the relationship between the students IQ and key stage 2 results.

Choosing Data

To retrieve the data about the students I downloaded the information from the internet. To choose the data that I obtained, I will randomly pick 20 girls and 20 boys by circling their names and stating their IQ and key stage 2 results.

Results

I choose the following boys to examine -

3+4+3+4+3+4+6+3+4+3+3+5+2+4+4+3+3+4+4+5 = 70

70/20 = 3.5

The average key stage 2 results for the boys aged 15 and 16 is 3.5

84+103+89+80+84+98+116+90+104+90+87+110+74+100+102+91+84+103+100+122 = 1922

1922/20 = 96.1

The average IQ level for the boys aged 15 and 16 is 96.1

I also choose the following girls to examine -

Name - IQ - key stage results for English , Maths and Science - Average key stage result

- Sarah Armstrong - 94 - 4-3-3 - 3
- Hanah Barlow - 102 - 5-4-4 - 4
- Vicky Briddle - 104 - 4-4-5 - 4
- Emily Brown - 105 - 4-4-5 - 4
- Nadia Calik - 104 - 4-5-4 - 4
- Samantha Dean - 112 - 5-5-5 - 5
- Shelley Dorn - 117 - 6-6-6 - 6

- Jo Hamilton - 105 - 5-5-4 - 5
- Anne Holligworth - 103 - 4-4-4 - 4
- Donna Johnson - 100 - 4-4-4 - 4
- Sarah Kelly - 110 - 4-4-4 - 4
- Claire Lewis - 102 - 4-4-4 - 4
- Jenny McFadden - 97 - 4-3-3 - 3
- Nichole Morison - 102 -5-4-4 - 4
- Tanya Peterson - 90 - 3-3-3 - 3
- Sally Raphiell - 100 - 4-4-4 - 4
- Jennifer Skelley - 109 - 5-4-4 - 4

19.Sara Slater - 96 - 3-3-3 - 3

20.Angela Taylor-Wall - 106 - 4-5-5 - 5

3+4+4+4+4+5+6+3+5+4+4+4+4+3+4+3+4+4+3+5 = 80

80/20 = 4.0

The average key stage 2 levels for the girls, aged 15 and 16 is 4.0

94+102+104+105+112+104+117+92+105+103+100+100+102+97+102+92+100+109+96+106 = 1956

1956/20 = 97.8

The average IQ level for the girls, aged 15 and 16 is 97.8

Average Results

This average result shows that the girls I chose got better results than the boys.

The average IQ level results shows that the girls have got a higher IQ level than the boys.

From these results, I have already found a relationship, which is the average girl has a higher IQ and a higher test result from the boys.

Tally chart

These tally charts show the average level, which the students achieved. It measures this by using a tally and frequency method.

Boys

The average results shows that the majority of boys got level 3 or 4. There is only a small exception that achieved level 2, 5 or 6

Girls

The average results for the girls shows that the majority of girls got level 4. The other girls achieved levels 3, 5 or 6. However, this was a minority as only three students achieved level 3 and only two students achieved level 5.

Line Graph

The following line graph shows the average results that the boys and girls achieved in their key stage 2 results -

This line graph is another way of comparing the boys and girls average results.

The line graph shows that the girls achieved a overall better result as more girls achieved a level 4 than boys. However, more boys achieved a level 3 than girls.

Boys and Girls

This table shows how many people achieved each level. This includes data from both genders.
