Question

the frequency distribution of the values of variable X together with their frequency totals (fx) is called * marginal frequency distribution of X conditional frequency distribution of X marginal frequency distribution of Y conditional frequency distribution of Y

bas aj layi kyu tenu gussa ni aya -.-​

Answer 1

Answer:

Bivariate frequency distribution table:-

y/x 20-30 30-40 40-50 fy

20-30 11(2) 11(2) 1(1) 5

30-40 111(3) 11(2) 11(2) 7

40-50 11(2) 1(1) 1(1) 4

fx 7 5 4 16

marginal frequency distribution of english(x).

x 20-30 30-40 40-50 total

f 7 5 4 16

marginal frequency distribution of statistics (y).

y 20-30 30-40 40-50 total

x 5 7 4 16

conditional frequency distribution of y when x lies between 30-40.

y 20-30 30-40 40-50 total

f 2 2 1 5
