   Question

   Evaluate the following statements about transformation of scores:

   1. After standardizing raw scores, the scores will be approximately normally distributed.

   2. When raw scores are normalized, a non-linear transformation is performed.

   
   
   1. FALSE: Statement 1 and statement 2 are both true
   2. FALSE: Statement 1 is true and statement 2 is false
   3. TRUE: Statement 1 is false and statement 2 is true
   4. FALSE: Statement 1 and statement 2 are both false
   
   

   Solution

   Statement 1 is false: after standardization, the scores have the same distribution as the raw scores, which is not necessarily normal.

   Statement 2 is correct: when scores are normalized, you have to perform a non-linear transformation in order to change the distribution of the raw scores (make them more normally distributed).

   
   
   1. False
   2. False
