Compare and Contrast of As a group we chose a quantitative set of data which was the Forced Expiratory Volume in Liters. Using the Systematic Sampling Method, we chose every 20th number from the population sample totaling 35 samples. In the Excel program, the mean and standard deviation for the sample were calculated. The data was then copied into StatCrunch and a Frequency Histogram and a Box Plot were generated. Both the histogram and box plot were skewed to the right, but overall the data had a normal distribution. For the second sample, the Simple Random Sampling method used. The total population of Forced Expiratory Volume in Liters was entered into the StatCrunch program and a random sample from the population we generated totaling 35 samples. The data was then copied into Excel where the mean and standard deviation was calculated. Next, the StatCrunch program was used to generate both a Frequency Histogram and Box Plot. We found that both graphs were skewed to the left resulting in a non- normal distribution compared to the Systematic Sampling Method. The total Population Standard Deviation was Standard Deviation for the Systematic sample was The Standard deviation for the Simple Random Sample was higher with a measurement of This was much higher than the Total Population Standard Deviation and the Systematic Sample.
