The aim of this experiment is to determine whether childrens shoe sizes get bigger as they get older. The hypothesis will be tested by completing an experiment, then by examining the results it will be seen whether the hypothesis was right or wrong. Hypothesis – As children get older their shoe size increases Null Hypothesis – As children get older their shoe size does not increase. Method
It was decided to collect the data in form of a simple table. This was decided because only certain information was needed about an age and shoe size, therefore a questionnaire would not be suitable. Also, considering the investigation was mainly aimed at children, the table was the simplest way to collect the data. It was decided to ask the parents of the younger children what their shoe size was as it was assumed most younger children would not know their shoe size.
Design and Materials
The type of study completed is one which gives an outcome of qualitative data. Furthermore, this can then be shown to be ‘continuous data’, where the data can fall anywhere over a certain range and the scale is only restricted by the accuracy of measuring, in this circumstance, measuring children’s shoe sizes (Mathematics Enhancement programme 2000). The data were collected in form of a table (See Appendix A). This shows the number of participants so all were kept anonymous, the age of the child and then their shoe size
