  2. Maths data handleling

    I took a sample of 50 students from Mayfield high school, 10 from year 7 to year 11. I split them into girls and boys so all together there were 25 girls and 25 boys, 5 girls and boys in each year. I used the random number generator to get all of this sample by typing in the calculator 'Shift' 'Rand#' then when you get the number you times it by how many there are in the sample. Say there are 200 then you would do 'shift' 'rand#' times 200.

  3. Comparison of IQ means of all years

    A bigger sample is required to check whether hypothesis 1 was correct. Hypothesis 2- IQ levels of pupils doesn't depend on whether they are left or right-handed. In year 7 the mean IQ is higher for the left-handed (LH) then for the right-handed (RH). In year 9 it is the other way round. In year 11 the means are about the same for both the LH and RH groups. Hence, hypothesis 2 was correct. Hypothesis 3- There will be a higher number of children with an IQ lower than the mean for their year group; in all years; however there will be some pupils with a high IQ which will increase the mean.

  4. Discuss the role of genetics & cultural differences in the development of intelligence.

    There was no difference adopted children and a control group who remained with biological parents. By adolescence both groups had come IQ correlation with biological parents. This study suggests that genetics have a strong influence on IQ. Bouchard & McGue (1981) carried out a study into the relationship between IQ and genetics by using a twin study. They reviewed 111 studies of twins and concluded that the mean correlation of intelligence in identical twins is 0.86, whereas for fraternal twins it is 0.6. A criticism of this study is that people who share genetic similarities tend to share environmental similarities, which makes it unclear whether it is genetics or the environmental that affects intelligence.

  5. In this investigation I am going to look into the number of goals scored against the league position in the 2002/03 season.

    That should help me get accurate data. When I used the random number devise. Which was 'ran#' button on my calculator. They results where as follows- Number Team Goals 16 Aston Villa 42 4 Chelsea 68 1 Man Utd 74 18 West Ham 42 9 Man City 47 To find out if there is a link between league position and goals I will use a line graph. My Prediction is that they will be a strong coloration between the two.

  6. Data handling - Hypotheses- Is there any correlation between the children's favourite sport and favourite subject in yr 8.?

    Do girls have a higher IQ than boys? The graph I am going to use to show this piece of data is the frequency polygon. In order to do this I will need to construct 2 tally charts to represent boys and girls. To Boys Girls Here is my graph Result: from the graph I can conclude that the boys and girls have the same IQ so the group is average.
