# Mayfield High school

Mathematics coursework

Introduction

My second coursework for my Mathematics GCSE course is based on statistics. I have been provided with data from Mayfield High school. Mayfield is a fictional school. Mayfield School has 1183 students from year’s group 7 to 11. The data that is provided on each student includes, name, age, year group, IQ, weight, height, hair colour, eye colour, distance from home to school, usual method of travel to school, number of brothers and sisters, key stage 2 results in English, Mathematics and Science.

Hypothesis – The right-handed girls have an IQ number higher than the left-handed girls. I am going to investigate this hypothesis showing graphs and tables.

The next table shows how many students have in each year group.

The following table show the right and left-handed girls on school.

Right hand

I have collected 100 IQ number from the Mayfield High School based on right hand girls. The data is from different ages and year’s group.

I collected the following IQ numbers:

116, 105, 98, 69, 102, 101, 100, 104,103, 104,100, 99,100, 91, 122, 87, 90, 88,101, 100, 101, 103, 94, 94,105,100,102,102,100,103, 102, 90,107, 107, 106, 79, 99, 101, 106, 108,85,106, 100,93,107, 116, 100, 116, 112, 105, 108, 103, 90, 97, 95,102,102,100,99,102, 100, 90, 94, 103, 116, 106, 91, 91, 113, 105, 101, 107, 100, 90, 100, 103, 110, 104, 116, 113, 117, 101, 83, 106, 94, 92, 101, 112, 116, 104, 110, 117, 100, 114, 119, 112, 104, 104, 101, 108

Then, I draw a stem and leaf diagram to group the data.

Key: 6/9 = 69

10/0 = 100

Cumulative Frequency

The cumulative frequency graph showing the above table is on a separate paper.

Left hand

I have collected 100 IQ number from the Mayfield High School based on left handed girls. The data is from different ages and year’s group.

I collected the following IQ numbers:

98, 104, 116, 94, 115, 104, 76, 94, 88, 96, 100, 95, 88, 104, 117, 110, 105, 103, 103, 107, 105, 96, 94, 106, 107, 104, 94, 102, 104, 113, 100, 106, 96, ...
