1. Given the following data: 12, 42, 53, 14, 59, and 28. The range is 47.
2. If the standard deviation of a study population is 11, the population variance is 121.
3. A sample variance will be zero if each of the data values in the random sample has the same value.
4. The measure of dispersion is a numerical value that describes how widely the data are disperse about a central value.
5. In any data set, the mode will always be unique.
6. A single, extremely large value can affect the median more than the mean.
7. Mean and median are affected when a constant is added to each data values in a data set.
8. The mean is the most frequently observed value of the measurements of a study variable of interest.
9. The mean is not meaningful if extremely large or small values are found in the data set.
10. The value of the middle term in a ranked data set is called
