Analyse the Cycling Time-Trial Data Below

Analyse the cycling time-trial data below. Thirty-two elite cyclists were randomly allocated into one of four groups. Without using SPSS, calculate the mean and total for each group. The groups were as follows
i. Received caffeine and were told it was
ii. Received caffeine and were told it was not
iii. Received no caffeine and were told it was not
iv. Received no caffeine but were told it was
Group 1-
v. Mean: 45.9 km
vi. Total:367 km
Group 2
vii. Mean:39.9 km
Viii. Total:319 km
Group 3
ix. Mean:38.9 km
x. Total:311 km
Group 4
xi. Mean:46.8 km
xii. Total:374 km
How would you calculate the total sum of squares?

A) SST = SSW + SSB
B) SST = SSW - SSB
C) SST = SSB / SSW
D) SST = SSB × SSW
