O True O False110 DETAILS MY NOTES The value for the standard deviation cannot be larger than the value for the range. O True O False 111 DETAILS MY NOTES What additional information is obtained by measuring on an interval scale compared to a ordinal scale? O whether the measurements are the same or different O the direction of the differences O the size of the differences O none of the above 112. DETAILS MY NOTES Although research questions usually concern a the actual research is typically conducted with a O sample, statistic O population, parameter O sample, population O population, sample 113 DETAILS MY NOTES A correlational study is used to examine the relationship between two variables but cannot determine whether it is a cause-and-effect relationship. O True O False105. DETAILS MY NOTES If a population has a variance of 4, then the population standard deviation is 16. O True O False 106 DETAILS MY NOTES A population has A = 20 and o = 5. If five points are added to every score in the population, the new set of scores will have u = 25 and o = 10. O True O False 107 DETAILS MY NOTES If every score in a population is multiplied by 3, then the population standard deviation will also be multiplied by 3. O True O False 108 DETAILS MY NOTES In a distribution with A = 40, the largest score is X = 45 and the smallest score is X = 35. For this distribution, the standard deviation cannot be greater than 5. O True O False 109 DETAILS MY NOTES Adding 10 points to every score in a distribution will not change the value of the standard deviation. O True
