TASK TITLE: REACTION TIME

QUESTION:         WHICH IS YOUR MOST DOMINANT HAND?

IS THERE A DIFFERENCE BETWEEN YOUR RIGHT AND LEFT HAND?

INTRODUCTION:

        In this coursework my task description is to see how fast I can catch a reaction time ruler. I have to do this with both my hands and see the difference between the hands. I am going to collect my data from: Myself – right and left hand                - year 11

        Partner – right and left hand                - year 11

         3 boys – right and left                        - year 11

3 girls – right and left hand                - year 11

3 men – right and left hand                - adults 18+

        3 women – right and left hand                - adults 18+

Using my data I am going to represent it in stem and leaf diagrams, tally charts, averages, bar charts and scatter graphs.

PREDICTION

        I PREDICT THAT YOUR WRITING HAND IS YOUR DOMINANT HAND AS I THINK THAT YOU REACT FASTER TO THAT HAND BECAUSE YOU ARE USE TO THAT HAND.

AVERAGES

Now I am going to find out the average for the people whose data was taken so I can see the average of each hand and then figure out which hand looks dominant.

MYSELF –         RIGHT HAND – 16.3  

LEFT HAND – 15.5

PARTNER –         RIGHT HAND – 15.85

LEFT HAND – 13.55

BOY 1 –         RIGHT HAND - 16

LEFT HAND - 16

BOY 2 –         RIGHT HAND - 16

LEFT HAND – 16.95

BOY 3 –         RIGHT HAND - 15

LEFT HAND – 15.65

GIRL 1 –         RIGHT HAND – 16

LEFT HAND – 18.4

GIRL 2 –         RIGHT HAND – 13.55

LEFT HAND – 14.9

GIRL 3 –         RIGHT HAND – 18.6

LEFT HAND – 18.8

MAN 1 –         RIGHT HAND – 13.6

LEFT HAND – 13.6

MAN 2 –         RIGHT HAND – 13.6

LEFT HAND – 14.05

MAN3 –         RIGHT HAND – 12.1

LEFT HAND – 15.3

WOMAN 1 –         RIGHT HAND – 14.15

LEFT HAND – 11.1

WOMAN 2 –         RIGHT HAND – 11.9

LEFT HAND – 12.45

WOMAN 3 –         RIGHT HAND – 14.2

LEFT HAND – 13.85

STEM & LEAF

Now I am going to show my data in stem and leaf diagrams. As I am comparing my data between the right and left hand I am going to use back to back Stem & Leaf diagrams. The data for the right hand would be one side and the data for left hand would be another and this way it would be much easier for me to see the differences.

As you can see that I have put all the data in a tally chart and then makes it easier for me to recognise the differences between the teenagers and adults. By looking at the tally chart you could see whether there is a difference between the year 11 and adults. You could see the amount of tally’s for each interval for each person.

    You can find a general formula allowing you to achieve maximum area by using algebraic expressions for the height length and width. 20 cm is the length and width of the square, therefore 20 = 2H + L Rearranging this it becomes L = 20 - 2H The formula for
