The heights of 16-18 year old young adults varies between males and females. My prediction is that the majority of males are taller than females.
Statistics coursework S1 Task A: Measurements The heights of 16-18 young adults varies between males and females. My prediction is that the majority of males are taller than females. I have decided to take a sample of 100 16-18 young adults from Havering Sixth Form College and measure their heights with a tape measure. My two populations will be male and females and I will obtain 50 male heights and 50 female heights. I have chosen to take a sample of 100 because small sample sizes may give inaccurate results whereas a larger sample size may be impractical and time consuming. Therefore I feel a sample size of 100 will give a efficient set of results and a meaningful conclusion could be deduced. To insure that the data I collected wasn't biased I didn't look at each persons height to ensure that the data I collected was even for both populations and within both populations. Also because height isn't affected by whether you are athletic or not or whether you eat lots or who you are friends with, the data I collected cant be bias for that aspect of my data collection and also I didn't collect my data at a modeling studio, of which nearly everyone there would be over 6ft and would make my data collection bias and unfair. So overall the data I collected wasn't bias and was accurate to use for my investigation. I decided to investigate the difference in heights between
