Task 5: Visualization Exercise: Normal Curve + Standard Scores + Raw Scores + Interpretation

This is an exercise to help solidify your understanding by visualizing how positions within a data set relate to the normal curve, standard scores, and interpretative ranges.

Complete the table.

For the Z distribution: The mean is 0 and the standard deviation is 1 .

For the T distribution: The mean is 50 and the standard deviation is 10

For the IQ distribution: The mean is 100 and the standard deviation is 15 .

For HR and RR: Use the whole number rounded mean and standard deviation from Task 3.

 

 

Scale -3 SD      -2 SD    -1 SD     Mean +1 SD    +2 SD     +3 SD

Z                                                       0

T                                                       50

IQ                                                     100
