Question
CHAPTER 1-Defining and Collecting Data #2-Fill in the blank: arises from failure to collect data on all items in the sample and results in a nonresponse bias. b) When talking about numerical data and variables, those variables that result from a measurement process while are those variables that result from a counting process. are c) Of the four levels of measurement, categorical data are classified as either or while numerical data are classified as when there is a starting point or true zero, but as__when there is no true zero. d) In a subject matter. Although experts may be well informed, you cannot generalize their results to the population sample, you collect the opinions of preselected experts in theExplanation / Answer
(a) Non Response Error-Arises from failure to college data on all items in the sample and results in Non Response Bias.
(b) Quantitative variables consist of numerical measurements of counts and numbers used for calculations.
categorical variables are those numeric or nominal variables that take a finite, limited, countable number of possibilities or values (e.g. number of children in families)
(c) Discrete/categorical variables can be further categorized as either nominal or ordinal variable
Ratio scale: An interval measure that includes a natural starting point (absolute zero)
Interval scale-no natural zero starting point,
(d) Judgement sample
