Data analysis
Data from the population are always included in the sample data. The expectation is that the sample parameters may differ from or coincide with population values. To select a representative sample of the population data, Random Sampling should be employed. Excel RAND () This tool generated a random sample to conduct this study. This allowed for the selection of an appropriate random sample to conduct this investigation. These descriptive statistics closely match the National summary statistics using the random sample data. The observed divergence in the results isn’t significant.
