Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15 is 3.
According to the given question.
Tobi scored 145 marks on an iq test.
⇒ x = 145
Mean, μ = 100
Standard deviation, σ = 15
As we know that,
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
And it is calculated by formula
Z = x -μ/σ
Where,
Z is a Z-score
μ is mean
x is the observed value
Therefore,
The Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15
= 145 - 100/15
= 3
Hence,Z-score if Tobi scored 145 on an iq test with a mean of 100 and a standard deviation of 15 is 3.
