Match List I (Total sum of squares (TSS) and Residual sum of squares (RSS)) with List II (R-squared of the regression model) and choose the correct answer from the options given below.
List I
i.RSS = 5, TSS = 20
ii.RSS = 5, TSS = 25
iii.RSS = 10, TSS = 25
iv.RSS = 12, TSS = 32
List II
a.0.62
b.0.75
c.0.8
d.0.6
Ai-a, ii-b, iii-c, iv-d
Bi-b, ii-c, iii-d, iv-a ✓ Correct
Ci-c, ii-d, iii-a, iv-b
Di-d, ii-a, iii-b, iv-c
Correct answer: (B) i-b, ii-c, iii-d, iv-a
Explanation
R squared equals one minus RSS over TSS, giving i-b, ii-c, iii-d, iv-a.
Model i, 5 over 20, yields 0.75.
Model ii, 5 over 25, yields 0.80.
Model iii, 10 over 25, yields 0.60.
Model iv, 12 over 32, yields about 0.62.
A higher R squared means residual variation is a smaller share of total variation.
