PPH4811 ASSIGNMENT 1 2026
DUE MAY 2026
Data: 12.0, 10.5, 9.5, 6.3, 13.5, 12.5, 7.2 (units: g/dL)
1. Measures of central tendency – formulas and steps
(a) Mean
Formula:
xˉ=∑i=1nxinxˉ=n∑i=1nxi
where xixi = each observation, nn = total number of observations.
Sum all 7 values:
12.0+10.5+9.5+6.3+13.5+12.5+7.2=71.512.0+10.5+9.5+6.3+13.5+12.5+7.2=71.5
Divide the sum by the number of patients (n = 7):
xˉ=71.57=10.214...≈10.2xˉ=771.5=10.214...≈10.2
Mean haemoglobin concentration = 10.2 g/dL
