“Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the following data: Favorite colors chosen by participants in a survey (red, blue, green, etc.).”

Given the following Data set (2,11)(3,19)(4,10)(5,8)(6,2)(7,5)(9,25)(12,56)   Perform a Linear Regression  A. Report the Model Equation (in the form y = mx+b) for the data set. (round to the nearest hundredth) B. Report the r value C. Does the data set appear to follow a linear relation (is a linear regression a good tool to use on the data set), why or why not.

“Describe the following data as Qualitative or Quantitative and explain why: A. The species of trees in an old-growth forest (e.g., oak, maple, pine, etc.)B. The heights (in meters) of the trees in the same forest.”

A sample of reaction times (in seconds) is recorded for a group of five individuals under two different conditions: with caffeine and without caffeine. Find the coefficient of variation for each of the two samples. With Caffeine Without Caffeine 0.42 0.55 0.38 0.62 0.50 0.48 0.46 0.60 0.41 0.58 A. The coefficient of variation for the reaction times with caffeine is? B. The coefficient of variation for the reaction times without caffeine is?
