The fundamental concept underlying statistical inference is that (A) through the use of sample data we are able to draw conclusions about a sample from which the data were drawn. (B) through the examination of sample data we can derive appropriate conclusions about a population from which the data were drawn. (C) when generalizing results to a sample we must make sure that the correct statistical procedure has been applied. (D) Two of the above are true. (E) All of the above are true. 0022v02 Statistics has been called “the science of data”. It involves (A) planning for the collection of data. (B) collecting and organizing sets of data. (C) describing sets of data for their own sake. (D) describing sets of data to help describe the populations such data sets are drawn from. (E) describing sets of data to make inferences about the populations such data sets are drawn from. (F) All of (A)-(E) are true. (G) All but one of (A)-(E) are true. 0074v01 Which of the following types of data has the most demanding assumptions? (A) nominal data (B) ordinal data (C) data on an interval scale (D) data on a ratio scale 0075v01 Parameter is to statistic as: (A) Greek is to English (B) infinite is to finite (C) population is to sample (D) hypothetical is to observed (E) Two from (A)-(D) are correct. (F) Three from (A)-(D) are correct. (G) All from (A)-(D) are correct. 0076v01 One key difference between descriptive statistics and inferential statistics is (A) having one or more variables (characteristics) of the population and/or sample to be examined. (B) identifying patterns based on the data. (C) having a measure of the reliability (i.e., the probability of being correct) for any conclusions reached in examining the data. (D) Two from (A)-(C) are correct. (E) All from (A)-(C) are correct. 0077v01 In making a statistical inference, one must (A) be interested in a population. (B) be interested in one or more characteristics of the population. (C) have a sample of units from the population on which to base the inference. (D) estimate a parameter of the population as a part of the inference. (E) have an estimated probability of being correct in the inference made. (F) All from (A)-(E) are correct. (G) All but one from (A)-(E) are correct.. 0078v01
