The results help the experimental hypothesis stating subjects in the dark chocolate condition will significantly score their happiness higher as compared to those in the little chocolate condition. There had been lots of control over the study as an experiment was used and the independent variable was entirely controlled. This research approach also ensured that all subjects were treated similarly as possible. They almost all heard the same debriefing but the standardised instruction differed for the a couple of groups, as it included one group eating dark chocolate as well as the other not.

A strength regarding using the independent measures design is that each issue took part in just one of the a couple of conditions avoiding order effects. But participant variables may have been a challenge with regard to example the participants in the chocolate condition may have been more cozy with sharing their joy score than those in the other group. The sample included equal number of males and females; therefore the study was not biased towards sex. But the results are unable to be generalised to folks outside the age selection 16-19 years and to those who are not students. Also, the outcomes don’ t represent some other towns and can simply be generalised to English students. Therefore many generalisations cannot be made.

Demand characteristics might have occurred as the topics were informed in typically the standardised instructions that they will be answering concerns. There is also the particular possibility that subjects may have rated their happiness on such basis as what they thought had been expected rather than just how happy they really have been at the time. Nevertheless demand characteristics were likewise minimised by asking some other questions rather than merely the critical question.

To improve the research, subjects from different villages, nationalities and age organizations could possibly be used to see if similar results are found and this would permit the findings to get generalised to some much wider population. Subjects: An chance sample of 30 dark-colored and white college learners aged between 16-19 years. 15 males and 12-15 females. Subjects were picked during college time plus randomly assigned as one regarding the two groups.

Procedure: Informed consent was gained from just about all participants and they had been checked for any allergies or illness that may be affected by chocolates (Appendix 1, Page7). The study occurred in the quit room, where only the participants were existing. The standardised instructions had been read to both groups (Appendix 2, Page 7). Group 1 (chocolate condition) did the experiment very first. All 15 participants in this group were provided with 4 squares of dark chocolate. Once they ate the chocolate, they filled in the particular short questionnaire. Then they will left the room and immediately group 2 arrived and filled in the particular same questionnaire but these people were not given any chocolate. Both of the particular groups were thanked plus debriefed (Appendix 3, Web page 8).

All participants were treated similarly. The experiment took location in the same area ensuring identical surroundings. All subjects were aware that they will had the rights to withdraw at anytime (Appendix 1 & 2, Site 7). The only variation was that one party were given chocolate before they filled in the questionnaire but the some other group has not been. The dependant variable was the answer in order to: Rate your happiness about the scale of 1-5. This was the essential question; the other concerns were there just to decrease demand characteristics. In order to find out there whether the results had been just due to possibility an inferential statistical check was performed. The test used persistent groups style; therefore the Mann-Whitney Oughout test was used in a 0. 05 level associated with significance. A significant distinction between the happiness associated with the two groups was looked for.

It was found that the subjects in the particular chocolate condition rated their happiness higher than individuals in the no chocolates condition. This indicates of which chocolate has an influence on a person’ s happiness. The table below shows the mean, median & mode. They’ve been applied to find out the particular central tendency for typically the happiness scores for each of the groups. (See Appendix 5, Page being unfaithful for raw data).
