WebVariance means to find the expected difference of deviation from actual value. Therefore, variance depends on the standard deviation of the given data set. The more the value of variance, the data is more scattered from its mean and if the value of variance is low or minimum, then it is less scattered from mean. WebPedro can report his findings as a list or a data display such as a dotplot where each dot represents one response. Center and spread are ways to describe data sets like this. Center describes a typical value of a data point. Two measures of center are mean and median. Spread describes the variation of the data. randy berry fairmount indiana
