And sometimes this will be called the sample variance. But it's a particular type of sample variance where we just divide by the number of data points we have. And so people will write just an n over here. So this is one way to define a sample variance in an attempt to estimate our population variance. But it turns out-- and in the next video I'll give you an intuitive explanation of why it... Statistics: Variance, Standard Deviation and Coefficient of Variation Stats: Measures of Variation- Jerry Wu. Mode The mode of a variable is the value or category with the highest frequency in the data. Most commonly used with qualitative data. Median Middle value of the data when the data are arranged from lowest to highest. If the sample size n is odd the median is (n+1)/2th value, if n is

What purpose does calculating variance serve in statistics

Variance gives you the spread of the data, or the spectrum in your phenomenon. Ex: If you have all kinds of ages using your virtual reality product, don't just advertise it to kids, since the variance is high....
Variance and standard deviation for grouped data: Following are the basic formulas used to calculate the population and sample variances for grouped data. and : where is the population variance, is the sample variance and m is the midpoint of a class. In either cases, the standard deviation is obtained by taking the positive square root of the variance. Again, the following computational
