It's a generalisation of how many conditional distributions would be there from bivariate frequency distribution. Considering the same example as given, we shall have 5 + 5 = 10 conditional distribution of students such as : 1. Conditional Distribution of Marks in Statistics for Students having Mathematics Marks between 0 - 4 2. Conditional Distribution of Marks in Statistics for Students having Mathematics Marks between 4 - 8 ... .... 6. Conditional Distribution of Marks in Maths for Students having Statistics Marks between 0 - 4 7. Conditional Distribution of Marks in Maths for Students having Statistics Marks between 4 - 8 ... ...

Can any one solve this question with clear explanation ?

Regression coefficient of y on x = k Similarly regression coefficient of x on y = 4 We know, when we multiply these 2 coefficients, we get r^2 which implies r^2 = 4k. Value of r lies between -1 to 1, including nos. So, 0 </ =(r^2) </= 1, implies 0 </= (4k) </= 1 or 0 </= k </= (1/4)

Sir in the frequency distribution we distribute frequency over the intervals (if its grouped frequency distribution) and over the terms or values if its (if its simple frequency distribution) Then in theoretical probability distribution do we distribute probability? If yes over what do we distribute probability? What is the difference between theoretical distribution and random variable?
