Statistics Many different types of statistics are used when conducting a population analysis. Normal distribution will be use to show the outliers in the data, since normal distribution shows what 'normal' data points would look like. Standard deviation can be used hand in hand with normal distribution to measure how the data points are distributed; the higher the standard deviation, the more spread out the data points are. This means that if my data points were 1, 2, 3, 4, and 5, the standard deviation would be much smaller than if they were 1, 29, 39, 74, and 299. Continuing, variance measures how far each data point is from the mean of the data set; as a result, I will need to calculate the mean. Variance also shows how spread out the data is. After all the manipulation of the data sets are complete, I will need to use these calculations to determine whether my null hypothesis or hypothesis is correct and how much error I have. In regards to testing my hypotheses, I wi
