Question 9

Robert stands three times on a pair of scales in a period of 5 minutes.The first time he weighs 92 kg,the second time he weighs 102 kg and the third time he weighs 95 kg.What conclusion can we draw based on this information on the pair of scales?

Question 12

Interval and ratio variables are also called metric variables.

Question 13

A characteristic of a variable on interval level is that it has an absolute zero point.

Question 14

With face validity,the validity is tested statistically.

Question 15

Cronbach's alpha can only be used when a variable is measured through several statements or questions.

Question 16

Cronbach's alpha can only be used for metric variables.

Question 17
