2. What are the four data scales? You may have read that anearthquake somewhere measured 6 on the Richter scale. The Richternumber R is used to quantify the strength of earthquakes. TheRichter number is defined as R = 10log(A) + constant. What is thedata scale of the Richter number variable? What role do data scalesplay in developing an operational definition? Explain the type ofresearch hypothesis required to study the following researchquestion: Do earthquakes of strength greater than 6 on the Richterscale cause thousands of deaths?
