While the central tendency, or average, tells you where most of your points lie, variability summarizes how far apart they are. This is important because the amount of variability determines how well you can generalizeresults from the sample to your population. Low variability is ideal because it means that you can better predict information about ...
The rangetells you the spread of your data from the lowest to the highest value in the distribution. It’s the easiest measure of variability to calculate. To find the range, simply subtract the lowest value from the highest value in the data set. Because only 2 numbers are used, the range is influenced by outliersand doesn’t give you any informatio...
Theinterquartile rangegives you the spread of the middle of your distribution. For any distribution that’s ordered from low to high, the interquartile range contains half of the values. While the first quartile(Q1) contains the first 25% of values, the fourth quartile (Q4) contains the last 25% of values. The interquartile range is the third quarti...
The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each score lies from the mean. The larger the standard deviation, the more variable the data set is. There are six steps for finding the standard deviation by hand: 1. List each score and find their mean. 2. Subtract the mean from each sco...
The variance is the average of squared deviations from the mean. A deviation from the mean is how far a score lies from the mean. Variance is the square of the standard deviation. This means that the units of variance are much larger than those of a typical value of a data set. While it’s harder to interpret the variance number intuitively, it’s im...
