Question 1

    Which of the following statements about the Chi Square statistic is NOT true?

  1. Chi Square squares the differences between observed and expected frequencies, thus inflating the true difference.
  2. Chi Square is not calculated from observed and expected frequencies.
  3. Chi Square is artificially inflated by sample size.
  4. Measures of association need to be on standardized scales with a 0 meaning no relationship and 1 meaning a perfect relationship. Chi square can be virtually any positive number.

Question 2

Which of the following Phi statistics would represent the weakest relationship?

  1. .02
  2. .15
  3. .28
  4. .37

Question 3

    What statistic tells you the likelihood of drawing a sample with a measure of association at least as strong as the one drawn from a population where that measure of association is zero?

  1. Significance Statistic
  2. Cramer's V
  3. Phi
  4. Alpha Level

Question 4

    What is the null hypothesis for the relationship between age and opinions on abortion?

  1. There is a relationship between age and opinions on abortion in the sample.
  2. There is no relationship between age and opinions on abortion in the population.
  3. There is a relationship between age and opinions on abortion in the population.
  4. There is a relationship between age and opinions on abortion in the population.

Answer True or False for the following: 1. Chi-square requires assumptions about the shape of the population distribution from which a sample is drawn. 2. Goodness of fit refers to how close the observed data are to those predicted from a hypothesis. 3. The null hypothesis (H0) states that no association exists between the two cross-tabulated variables in the population, and therefore the variables are statistically independent. 4. High chi square values indicate a high probability that the observed deviations...
