In our presentation, we will be using statistical hypothesis testing to compare two samples. The two sample t-test is commonly used to determine if the mean (average) difference between two populations is actually significant or merely due to random chance. This method is used when the following criteria is met: data values are gathered from two populations, the data values/samples are independent from one another, the sample size has to be greater than 30, and the samples follow a normal distribution. Our presentation will focus on COVID-19 data analysis.
