Answer:

b) Discrete

c) Ratio        

Step-by-step explanation:

We are given the following in the question:

Experiment:

Evaluate the effectiveness of different study strategies. All students were then given a test on the passage material and the researchers recorded the number of correct answers.

a) The dependent Variable

The number of correct answers given is the dependent variable because it depends on the number of times the passage is read.

b) Nature of dependent variable.

  • It is a discrete variable.
  • Since, the number of questions will always be expressed in whole numbers and cannot be expressed as decimals.
  • They are always counted and not measured.

c) Scale of measurement

  • Ratio is used to measure the dependent variable because true zero for the number of correct questions answered exist.
  • If the measure is zero that means truly no questions were answered correctly.
