A z-score<span> is the number of standard deviations from the mean a data point is.
</span>
Standard deviation explains by how much the members of a group differ from the mean value for the group.
Using the z-score formula:
z = ( x - μ ) ÷ σ
Where;
x = score
μ = Mean
σ = Standard deviation
Z- Score (Tara) = ( 52 - 64 ) ÷ 8
= - 12 ÷ 8
= - 1.5
Z- Score (Jamal) = ( 82 - 64 ) ÷ 8
= 18 ÷ 8
= 2.25
Z- Score (Samuel) = ( 66 - 64 ) ÷ 8
= 2 ÷ 8
= 0.25
