Effect of Advertisement on Consumption of Unhealthy Food among Children - Lab Report Example

Lab Report Student’s Name Institutional Affiliation Effect of advertisement on consumption of unhealthy food among children Research hypothesis The following hypothesis will guide this study 1. H1: There is no effect of advertisement type and age on the number of tiny teddies consumption among children 2. Ha1: There is effect of advertisement type and age on the number of tiny teddies consumption among children 3. H2: There is no effect of the amount of time since children last ate on number of tiny teddies consumed 4. Ha2: There is effect of the amount of time since children last ate on number of tiny teddies consumed 5. H3: There is no difference in numbers of tiny teddies consumed between children who like or do not like tiny teddies. 6. Ha3: There is difference in numbers of tiny teddies consumed between children who like or do not like tiny teddies The three above hypothesis will be tested and conclusion written based on the research findings on whether to accept or reject the null hypothesis above. Research methodology Participants: The participants in this research are children aged 3-4 randomly selected to respond to experimental research. They were placed under controlled environment and are of both gender that is male and female. At the beginning of the program they were provided with a bowl containing 30 Tiny Teddies (small biscuits). Researchers counted how many Tiny Teddies each child at during the program. Materials: The behaviour were being recorded in the laboratory sheet where data were collected before they could be prepared for analysis. Children were recruited from advertisements placed on online discussion forums aimed at parents in the Canberra area, and testing sessions occurred in a laboratory set up as a ‘mock living room’ (containing a television and comfortable chairs) on campus at the University of Canberra. Children were tested individually with a parent present. Research design: Research methodology is the framework used in finding the research question. It entails the approach, sample size and techniques in reaching the conclusion. This study involves quantitative techniques of investigating the research data. In this study a sample size of 58 children were randomly picked for the experiment. Both were from different sex. The age of children were between 3 to 4 years in the sample population. This study will involve one sample t-test and paired t-test for the hypothesis. One sample t-test can be described as a statistical procedure which is used to establish whether a sample of observation could have been generated by a process with a specific mean. In this case, we have two hypothesis which will be tested, that is null and alternative hypothesis. In the first case, it assumes that some difference exist between the true mean while null hypothesis assumes that there is no difference between the means exist. Given a sample data, the one simple t-test will help us establish whether null hypothesis is rejected or accepted. The one simple t-test will be used in testing the third hypothesis which states:- 1. H3: There is no difference in numbers of tiny teddies consumed between children who like or do not like tiny teddies. 2. Ha3: There is difference in numbers of tiny teddies consumed between children who like or do not like tiny teddies We will be investigating the difference in means of these numbers and making conclusion based on the analysis and research findings. For testing the first and second hypothesis, the independent t-test will be very vital for this test. It will help in establish whether there is difference between the groups, which is male children and female children using the level of advertisement. The study will also carry out the regression analysis to establish the relationship that is whether there is relationship between consumption of unhealthy food and advertisement among children. We will carry out simple linear regression to establish the relationship of the two variables and make a conclusion. Analysis and Result Descriptive statistics From the results, Sex (N=58, M=.5690, SD =.49955), Age (N=58, M=1.5345, SD =.50317) Type of advertisement exposed (N = 58, M =1.5000, SD = .50437), Number of minutes since last time (N=58, M = 103.0690, SD = 75.73079), Number of tiny teddies eaten (N = 58, M =11.0690, SD =2.60136) Parent reported preference (N =58, M = .3966, SD =.49345) One sample T-test We test the third hypothesis that states:- 1. H3: There is no difference in numbers of tiny teddies consumed between children who like or do not like tiny teddies. 2. Ha3: There is difference in numbers of tiny teddies consumed between children who like or do not like tiny teddies Test Value = 0 t df Sig.
