Brianna received an overall IQ score of 117 on the Wechsler Scale. This means that Brianna has scored approximately____________
Tresset [83]

Using the normal distribution, it is found that the correct option is:

  • D. 1; 100

In a <em>normal distribution</em> with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

  • It measures how many standard deviations the measure is from the mean.

In this problem:

  • The mean on the Wechsler Scale is of 100, hence \mu = 100.
  • The standard deviation is of 17, hence \sigma = 17.
  • Brianna had an score of 117, hence X = 117

Then:

Z = \frac{X - \mu}{\sigma}

Z = \frac{117 - 100}{17}

Z = 1

Hence, the option d is correct.
