Maths Data handling think boys watch more TV than girls because boys have less work to do than the girls.

Extracts from this document...

Introduction

*Data Handling*

Introduction:

My data handling is based on a school called Mayfield high school; my job will be to investigate “Which gender watches an average number of hours TV per week.” “Which gender are taller boys or girls?” “Weight between boys and girls”

Hypothesis:

  1. I think boys watch more TV than girls because boys have less work to do than the girls.
  1. I think that boys are taller than girls in some ways.
  1. I believe that girls weight less than boys because the girls are more into a healthy diet.

*Plan of Action*

For my investigation my data will be presented in tables to show my results. I will be calculating the median and mode.

I will be using Secondary data because I already have my data.

For my first hypothesis (

Key: 100/10=100

Median for females = 13+1/2=7th value (18 hrs)

Mode=0

Median for Males=17+1/2= 9th value (15 hrs)

Mode=4

After doing a stem and leaf for both male and female I have found out that females watch more TV than males.

This shows that’s my hypotheses is incorrect because males watch less TV than females.

“I believe that boys are taller than girls.”

Modal class=41-50 occurs 6 times

Median=16+1=17/2=8.5

After doing a Modal class for both female and male I found out that males weight more than females. This proves that my hypothesis is correct.

*Overall conclusion*

After doing my entire hypothesis I have found out that some of my hypotheses are correct and some aren’t. For my first hypothesis I predicted that “Boys watch more TV than girls per week” after doing all my calculations I had found out that my calculations were incorrect, after all girls watch more TV than boy.

For my second Hypothesis I predicted that “I believe that boys are taller than girls.” In my calculations the results were correct. In my third hypothesis I predicted “I believe that girls weight less than boys because the girls are more into a healthy diet.” In my conclusion my answer was correct because boys are heavier than girls.
