2) formula of karl pearson's coefficient of correlation

Answer 1

Hello !

1.The Laspeyres Index is calculated by working out the cost of a group of commodities at current prices, dividing this by the cost of the same group of commodities at base period prices, and then multiplying by 100. This means that the base period index number is always 100.

2.The Karl Pearson's product-moment correlation coefficient (or simply, the Pearson's correlation coefficient) is a measure of the strength of a linear association between two variables and is denoted by r or rxy(x and y being the two variables involved).

Hope It Helps u :)
