The Mean grams of Fat in the fast foods Fat (g)

The Trimmed Mean Fat (g) Do you notice that one particular value is possibly an outlier. In order to better compute a “truer” average we will use a “Trimmed” mean.

The Trimmed Mean The trimmed mean has the advantage of being relatively resistant to outliers. The trimmed mean is computed just as an ordinary mean...except. a pre-specified percentage of the extremes is omitted. Consider the 5% trimmed mean. The left-most (lowest) 5% and right-most (highest) 5% of the data are excluded; from the remaining observations the mean is found. So, the 10% most "extreme" data (5% on either side) is omitted before computing the mean.

The Weighted Mean weighted mean  The weighted mean is used when the values in a data set are not all equally represented. weighted meanof a variable X  The weighted mean of a variable X is found by multiplying each value by its corresponding weight and dividing the sum of the products by the sum of the weights.
