When a weighted mean is used, the variance of the weighted sample is different from the variance of the unweighted sample. The biased weighted sample variance is defined similarly to the normal biased sample variance: where, which is 1 for normalized weights.or example, consider the weighted mean of the point [1 0] with high variance in the second component and [0 1] with high variance in the first component.

No, grapefruit is not a calorie-free fruit, as some diets would have you believe. Despite its reputation as a fat-burner, grapefruit has no special ability to burn away excess fat. But it is low in calories, and its soluble fiber content is decent enough to fill you up, discouraging you from overeating. So yes, grapefruit can help you lose weight, just not as easily as some would say. And it's nutritious, to boot. Grapefruit is a tart-tasting fruit not everyone enjoys. But for those who do, grapefruit offers a lot of nutrition for few calories.
