Question

The data below are from an independent-measures experiment comparing three different treatment conditions.

Treatment 1 Treatment 2 Treatment 3

0 1 6 k = 3

1 4 5 G = 36

0 1 8 X2 = 182

3 2 5

–––––––––––––––––––––––––––––––––––––

n = ____ n = ____ n = ____

T = ____ T = ____ T = ____

SS = ____ SS = ____ SS = ____

State the null and alternative hypothesis

Answer : From the above data we have,

For Treatment-1 : n=4, T= 4 and SS= Sum of squares = 12+32 = 10

For Treatment-2 : n=4, T= 8 and SS = Sum of squares = 12+42+12+22 = 22

For Treatment-3 : n=4, T = 24 and SS = Sum of squares = 62+52+82+52 = 36+25+64+25 = 150

NULL HYPOTHESES: There is no significant between all the three different Treatments.

i.e., The treatments are Independent.

ALTERNATIVE HYPOTHESES : There is a signifant between all the three different Treatments.

i,e., The treatments are dependent.
