## Introduction:

This is my GCSE data-handling project, throughout which I will be discussing the topic of how sleep deprivation affects the reaction and ability to estimate a minute.

Plan:

## Hypothesis

My hypothesis is:

• People who get more sleep will have faster reaction times than people who get less sleep
• People who get more sleep will be better at estimating a minute than people with less sleep.
• Females will do better than males. Hopefully the competitive attitude of many people to tests involving males versus females will make sure that the subjects are trying to get the best scores they possibly can, and this should reduce the number of anomalous results I receive. To test my hypothesis, I will need to collect data from a random sample of people.

The data I need to collect is:

• Age
• Gender
• Reaction Time
• Ability to calculate a minute
• How many hours of sleep they get a typical night

## Data Collection

I will collect the Age, and Gender and amount of sleep they get per night simply by asking the subject, but collecting results for the ‘ruler drop’ test will be slightly more complicated. Below I will describe the method I will use for all subjects.

To perform this experiment I will use a reaction timer. The tester will hold the ruler, and whilst standing ask the subject to put their thumb and first finger over the bottom of the reaction timer. To ensure all subjects have their fingers the same distance away from the ruler, I will turn the ruler sideways and ask the subjects to leave their fingers at the same width as the ruler when it is turned sideways. Once I’ve ensured their fingers are in the correct position, I will wait for a random amount of time before dropping the ruler. ...
