# Mean Deviation for Grouped Data

Mean Deviation for Grouped Data Mean Deviation about the Mean: Recall the arithmetic mean (x̄) of a discrete frequency distribution with n data points is obtained using the formula: x̄ = (ⁿ∑i=₁ xi fi)/ ⁿ∑i=₁ fi = (ⁿ∑i=₁ xi fi)/ N. Where, N = ⁿ∑i=₁ fi Now the mean deviation about the mean i.e., M.D Read more about Mean Deviation for Grouped Data[…]

# Vector Product of Two Vectors

Vector Product of Two Vectors The physical quantities may be broadly classified into the vectors and the scalars. The quantities with magnitude and direction both are known as vector quantities. What is a vector product? The vector product or the cross product of two vectors is a binary operation on two vectors in three dimensional Read more about Vector Product of Two Vectors[…]
