1. We cannot use Pearson correlation with variables measured at a
nominal or ordinal scale. 2. A score with a value less than or equal
to the mean will have a z-score that is less than or equal to zero. 3.
One reason for transforming X values into z-scores is that the set of
z-scores will form a normal shaped distribution.

Subjective wellbeing was measured among a sample of Statistics
students, with M = 150 and S2 = 25. Determine the z scores for the

The Research Methods and Statistic module is almost over. Assume that
the total marks were at an average of μ= 18 per assessment, and that
the distribution of total marks are normally distributed with σ= 10.
a. What is the proportion that a student would have a mark more than
24 mark if randomly selected?

The Welcher Adult Intelligence Test Scale is composed of several
subtests. On one subtest, the raw scores have a mean of 55 and a
variance of 25. Assuming these raw scores are form a normal
distribution. What is the probability of obtaining a raw score between
50 and 58?
