there are theree measures of central tendency: the mean, the median and the mode. Measures persion include the range, the standard deviation, and the variance (where the measure of central tendency is the mean), and the interquartile range (where the measure of central tendency is the median). Describe these measures and explain which of these measures you would use to provide an overview of (a) nomimal, (b) ordinal, and (c)interval data?

the table below shows the number of books the Jefferson Middle school students readeach month for nine months. Month Sept. Oct. Nov. Dec. Jan. Feb. Mar. Apr. May Number of Books 293 280 266 280 289 279 275 296 271 If the students read only 101 books for the month of June, which measure of central tendency will have the greatest change?A. The mean will have the greatest change.B. The median will have the greatest change.C. All measures will have an equal change.D. The mode will have the greatest change.

Use the Student Unit Load data.  Student Unit Load 3, 12, 6, 9, 6, 12, 15, 12, 7, 9, 3   Find the mean, median, mode, range, standard deviation and variance. Use the range rule-of-thumb to find significantly high and low scores. Write the 5-number summary. Find the z-score for x = 15 Is x = 15 unusual in terms of a z-score?

☐True ☐False The median is a better measure of central tendency when the data is skewed positively, but not when it’s skewed negatively.

Draw the box-and-whisker plot and give the five-number summary for each data set.

Which one?

Consider the data set given by, (11, 17, 18, 23, 25, 26, 26, 31, 31, 33, 41, 44, 45, 48, 53) Find the lower (first) quartile median upper (third) quartile mean. round to one decimal place. mode(s)

Which of these is an advantage of using a transformed score when reporting the score of an individual case? a. Transformed scores will allow the mean score to be reported. b. Transformed scores will be reported on the nominal level. c. Transformed scores provide a context for the individual's score d. Transformed scores provide a measure of variability.
