Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
Now that you know how to find the average—in other words,how to calculate the mean of a given set of data—it’s time to test what you’ve learned. In this section, we'll give you four math questions that involve finding or using the mean. The first two questions are our own, w...
After calculating the mean squared error, one must interpret it. How can a value of 8.83 for the MSE in the above example be interpreted? Is 8.83 close enough to zero to represent a “good” value? Such questions sometimes do not have a simple answer. ...
I was a virgin before getting married (only kissed three guys before my husband). Now…just because I didn’t have sex before I got married doesn’t mean that I didn’t have desire. I have always had a very strong sex drive. Unfortunately, I married someone who had/has no desire fo...
How to Find the Mean Absolute Deviation The process for finding the mean absolute deviation involves the following three steps. Calculate thesampleaverage by summing all observations and dividing by the sample size. Find the absolute deviation of all data points from the mean. Take the observed va...
{eq}Mean (class B) = (2+8+10+10+10) / 5 {/eq}, we obtain: Average score of class A is 8. Average score of class B is 8. For each score set, the absolute deviation can be calculated by finding out the distance between each value of the set and the set's average. ...
