The variance of a random variable is the expectation of the squared deviation of that variable from its mean.
There were significant variances between the test scores of the two groups.
When calculating the variance, you sum the squared differences from the mean.

The variance formula involves summing the squared differences between each data point and the mean, divided by the number of data points.
