Identify each of the following as examples of nominal ordinal interval or ratio scales of measurement. (4 points each)(Points : 24) Two hundred raffle tickets are sold. Your friend has five people in her family who each bought two raffle tickets. What is the probability that someone from her family will win the raffle?(Points : 4) Interval variables Nominal variables Ordinal variables Ratio variables A testable hypothesis Additional observations Mathematical symbols Numbers The alternative hypothesis The baseline hypothesis The null hypothesis The reasonable hypothesis 6.6 7.2 7.8 8.7 6 7 8 9 5 7 8 9 5 6 7 11 1.53 1.60 2.33 2.56 The mean mode and median are all equal The total area under the curve equals 1 The curve is specified by two parameters the mean and the standard deviation The curve extends to + and 3 standard deviations from the mean 34 68 95 99.7 Degrees of freedom Freedom factor Variability index Variation quotient Rejecting the null hypothesis when in reality the null hypothesis is true Rejecting the null hypothesis when in reality the null hypothesis is false Accepting the null hypothesis when in reality the null hypothesis is true Accepting the null hypothesis when in reality the null hypothesis is false purposive sampling convenience sampling cluster sampling stratified sampling mean standard deviation normal distribution number of subjects it is also known as the level of significance value is set by the researcher value is equal to the probability of a type I error all of the above are true Boys who play sports are not viewed as more attractive than boys who do not play sports Playing sports will influence how attractively boys are viewed Boys who play sports are more attractive than girls who play sports There can be no null hypothesis Accepted at the .05 level Rejected at the .01 level Rejected at the .05 level None of the above 22 20 11 10 If each participant is measured twice Whenever there are equal numbers of subjects in each group Whenever there are only two groups All of the above 34% 68% 95% cannot tell from the information given Mode Mean Median None of the above are affected Individual scores Frequencies Means Deviation scores Range Standard deviation Median Mode 102 285 150 204 Mean Very top Very bottom None of the above since z cannot be zero Frequencies Observed scores z scores Area Mean Range Interval All of the above Mean Median Mode Midrange 0.8 1.8 0.1575 0.55 The new mean distance is 8.2 miles. The new mean distance is less than or equal to 8.2 miles. The new mean distance is less than 8.2 miles. The new mean distance is greater than or equal to 8.2 miles.
