Dr. Flintstone wants to estimate the stability of muscle contractions in professional hockey players in two assessments performed on the same day separated by 30 seconds of rest. To measure contractility of the muscle, Dr. Flintstone uses a Camry Electronic Handgrip Dynamometer then calculates the average (mean) of two scores to assess stability in muscle contractions. Dr. Flintstone compares each hockey player's score to normative data published by the National Hockey League Trainers Association (NHLTA) for age-matched males. According to the NHLTA, the following values classify each hockey player's performance on this test: Weak = 0.00 to 36.80 kgs; Normal = 36.81 to 56.88 kgs; Strong Greater than or equal to 56.89 kgs. What level of measurement best describes these normative data used by the NHLTA? Question 4 options: Ratio Nominal Interval Ordinal
