Does children's shoe sizes get bigger as they get older?

Introduction:

I will be doing an experiment to investigate whether it is true or not that children's shoes sizes really increase as they get older. In order for me to prove this, I need to collect some data and to start with, I have to create a simple and short questionnaire and I will ask some of my friends and family who has children and could help me with this experiment by completing the questionnaire. My objective is to find out at the end of this investigation whether my experiment on children's shoe sizes is true or not true.

Aim:

The aim of the experiment is to find out if the children's shoe sizes get bigger as they get older. I want to know the relationship between the age of a person and their shoes size.

Hypothesis:

As children get older their shoes size increases.

Null Hypothesis:

As children get older their shoes size does not increase.

Method:

Design:

I made a short and simple questionnaire that I can send through online (social network) to my friends and family. I prefer this kind of method because I find it to be more accurate rather than just observing or give an approximation into a child's shoes size. Before sending the questionnaire to my friends and family, first thing I have done was to explain to them what this questionnaire was all about and why do I need to do this. And I also asked their permission before sending the questionnaire to my prospect participants. (A sample of questionnaire can be found in the appendix section)

Participants:

I used 30 boys and 30 girls on my research. I have 60 participants altogether. Age ranges from 1 year old up to 10 years old. I preferred to have 3 boys and 3 girls on each age. Because I want to know if there is any difference with gender in terms of shoe sizes and age. Since the method I have use to gather information is in the form of questionnaire, most of the questionnaire had been filled up by their parent on their behalf.

Materials:

The materials I have used on this experiment was: First, the questionnaire. Second, tables. In order for me to be organize I put all the data I collected in a table. I used plenty of tables on this experiment. Because in this way I can easily see the differences between a person's age and their shoes size. Third, I did some computations to get the average, range, and percentage. Fourth, is chart, I also used few charts on my investigation in order to picture out the data. And to clearly show whether my hypothesis is true. Fourth, I also have graphs. I also express my collected data in a form of a line graphs.

Procedure:

The following are the series of steps I did on the research I made to investigate my hypothetical question in order to determine whether it is hypothesis or null hypothesis.

I made a research on what does hypothesis and null hypothesis means. I made some reading about the topic, and thinks of what ways shall I do to collect some informations.
I created a simple and very short questionnaire to which I am going to send to my family and friends.
Then I made some lists on my next plan.
3.1 How many participants do I need?
3.2 How many girls? And how many boys?
3.3 What age brackets shall be my participants?
3.4 How will I send the questionnaire to my family and friends? Then after analysing those questions on my list. I checked on my friends lists on my facebook, twitter and skype who can be my prospect participants. I have to choose those people on my list that has children with age ranges from 1 up to 10 years old. Since the method I used to gather information is by the use of online social network, most of the people I will be asking are the parents of my participants.

I decided to send the questionnaire to all my family, relatives and friends through...
