Before raw data can be used as scientific evidence, it must be analyzed and summarized. One way of summarizing data is to find the mean, or average, of a set of data points. What method is used for calculating the mean?
The mean is simply the arithmetic average of all your raw data. This can be solved methodically by summing up all of the raw data points that you have. Take note how many raw data points you used, because this will be used to divide the sum. You will obtain the mean.
