The Weight of Your School Bag

Introduction:        My Chosen Topic is The Average Weight of the School Bag of Students in Year Ten at the Start of the week and just before it ends, as it seems to be a topic that no one actually thinks about all that much, but students sometimes complain how heavy there bags seem to be.

Hypothesis:        The Hypotheses I present on my topic are:

  • The Weight of the Bag will be Slightly Heavier as it is the start of the week, and students have a lot of work to turn in
  • The Weight of the Bag will be Slightly Lighter as it is just before the end of the week.
  • The Weight will also depend on the Miscellaneous Items the Student is carrying, so it is hard to determine which gender will have the Heavier bag but it should be about the same

Questionnaire: There was a little bit of difficulty in making the questionnaire for me, as I wanted specific results whilst keeping the questionnaire as simple as possible. First I had decided upon using Monday and Friday to compare but a lot of students have similar classes on both days so there wouldn’t much to compare whereas Thursday was just before the end of the week, and I decided to use it instead. There was also another problem that students did not have a scale to measure the weight of the Bag in Kilograms (Kg) and/or Pounds (Lbs) and /or Stone (St,), so I had to decide what scale to use, and decide to Use Pounds (Lbs) as it was much user friendly, and also on Some Bathroom Scales. Copies of the Different Types of Questionnaires that I made are included.

Plan:        I planned to use 9 different Form groups from Year Ten at my School, and all nine were chosen at random. From those clusters, 10 students would be chosen at random once again, from which there would be 5 male and 5 female students, totalling to 90 results, which I believed would me more than sufficient to prove/disprove my hypothesis. The exact same questionnaire sheet would be handed to every chosen one, who would have to turn it in ass soon as possible.

Results:        From the 90 Questionnaire that were handed out, only 72 questionnaires came back to ...
