To calculate the mean we are told by the formula to add up all these numbers, ages in this case, and then divide the sum by 10, the total number of animals in the sample.Īnimal number one, the cat Purr, is designated as X 1, animal number 2, Toto, is designated as X 2 and so on through Dundee who is animal number 10 and is designated as X 10. Purr is animal number one and is a 9 year old cat, Toto is animal number 2 and is a 1 year old puppy and so on. AnimalĮach observation represents a particular animal in the sample. The first number will be number 1 and the second number 2 and so on. If we list each value, or observation, in a column, you can give each one an index number. Let’s say we have a sample of animals from the local animal shelter and we are interested in their average age. The Σ symbol tells us to add a specific list of numbers.
