Question

Bring out the inconsistency in the following:

bYX = 2.6 and bXY = `1/2.6`

Sum
Advertisements

Solution

Given, bYX = 2.6 and bXY = `1/2.6`

Here, bYX and bXY have the same signs.

Also, bYX > 1 and bXY < 1

Also, for consistent data, the signs of bYX and bXY are same and bYX > 1, bXY < 1

Here, bYX. bXY = 1

∴ The given data is consistent.

For a certain bivariate data of a group of 10 students, the following information gives the internal marks obtained in English (X) and Hindi (Y):

  X Y
Mean 13 17
Standard Deviation 3 2

If r = 0.6, Estimate x when y = 16 and y when x = 10


Mean of x = 25

Mean of y = 20

`sigma_x` = 4

`sigma_y` = 3

r = 0.5

byx = `square`

bxy = `square`

when x = 10,

`y - square = square (10 - square)`

∴ y = `square`


The regression equation of y on x is 2x – 5y + 60 = 0

Mean of x = 18

`2 square -  5 bary + 60` = 0

∴ `bary = square`

`sigma_x : sigma_y` = 3 : 2

∴ byx = `square/square`

∴ byx = `square/square`

∴ r = `square`
