Question

10 multiple choice 10 points the pearson correlation measures the degree of linear relationship between two variables when the data (x and y values) consist of numerical scores from a/an: nominal scale of measurement ordinal scale of measurement interval or ratio scale of measurement none of the above

Explanation:

The Pearson correlation coefficient is used to measure the linear relationship between two variables. It requires that the data (X and Y values) be measured on an interval or ratio scale. Interval scales have equal intervals between values (e.g., temperature in Celsius or Fahrenheit), and ratio scales have a true zero point (e.g., height, weight). Nominal scales (e.g., gender, color) and ordinal scales (e.g., rankings) do not meet the requirements for the Pearson correlation.

Answer:

C. interval or ratio scale of measurement
