Introduction

GCSE COURSEWORK MODULE 2 MEMORY GAME 1. INTRODUCTION Hypothesis The hypothesis that this investigation will be testing is that women will remember more items than the men. This particular experiment has been chosen, as there is personal interest involved. This topic is often debated at home. It is also interesting to find out what particular items men and women would remember. Extended Investigation Hypothesis The second hypothesis that this investigation will be testing is that younger people will remember more items than the older people. 2. COLLECTION OF DATA Sample Chosen The sample size chosen for this investigation was 50. It was decided that this would be sufficient for this level of study as it is only intended to obtain a general understanding of memory capability. The sample that has been chosen for this investigation was a convenience sample. It was a convenience sample as the method of obtaining respondents was by opportunity (knocking on peoples doors). 25 male and 25 female friends, family, neighbours and work colleagues were chosen. Within each group of 25 there were 5 men and 5 women of the following age groups: 20 -30, 31-40, 41-49, 50 - 59, and 60 plus. This sample was appropriate to this investigation, as it would have proven difficult to conduct the memory game in any other sample type. Other sample types were eliminated for the following reasons: * Random sampling- this is usually conducted in public places such as outside a supermarket and it would difficult to display the items without a table. ...read more.

They are suited to this data as it is all in whole numbers. A frequency polygon would have been used for data such as temperature or time therefore a histogram is more appropriate for this study. A relationship is shown of the exact amount of items remembered. Graph 1 Histogram - The number of items remembered by men The modal class is seen in this histogram, which is 5. The data is closely grouped together in this chart. The majority of items remembered by men are in the range of 7 - 11. When there is an increase in the number of items it is more subtle than the women's. This histogram shows that men do not remember as many items as women. It also shows that the men overall remembered a closer number of items. This grouped frequency table shows the number of items remembered by women in the memory game investigation. Table 3.

Conclusion

When comparing the box plots the first graphs did not show any relationship. When comparing the frequency it gave much better results and favoured the women. This study could be further tested by: * Extend the time the respondents had to remember the items to see if it makes a difference. * Find out if the occupations of the respondents as it could effect how they remember. If they worked with certain items in the game they may remember them more. * Perhaps in a larger investigation there would be more accurate results of the population. It is difficult to make a statement on the difference between men and women on only a sample of 50. There was some bias in the investigation. The age groups for example were uneven. 20 -30 was a group of 10, 31 - 40 was a group of 9, 41 - 50 was a group of 9, etc. It would be fairer to have exact age ranges. There are factors that could affect a person's memory and that could be the time of day and whether they have eaten recently. If a person is tired or hungry they will not remember as well. It was discussed after the memory test as to what methods people used to remember items. Some mentioned that making up a story about the items or remembering the items in a pattern helped them to remember the items easier. Having groups using different methods to remember the items and see which group remembered the most could test these ideas. It would be useful to use secondary research in further investigations next time to compare results with previous investigations. ...read more.
