I know this data is a fair sample because it was chosen by Random using the Rnd button on the calculator.

I will now make a more useful representation of the data for my first line of enquiry.

  2. Conduct an investigation comparing height and weight from pupils in Mayfield School.

    I now hypothesise that separating boys and girls will produce stronger correlation between height and weight. (Please refer to the scatter graphs on page 10). The evidence supports my hypothesis that there will be stronger correlation between height and weight if boys and girls are considered separately.

    The graph looks like this: There are a few outliers visible in the graph. Therefore, to have more accurate results, these records must be replaced with data that makes more sense and follows the pattern. After making the adjustments, my graph now looks like this: This graph is a lot more sensible.
