(3 wds)14With an odd number of datavalues listed in order, the median is the _________ value.15A graphical display of the five-number summary is called a _________. It looks like a rectangle with a wire on each side of it.16_________ refers to how manycases are in a category.18Subtracting the differencebetween the maximum and minimum data values gives you the _________.19Each value in the sample orpopulation has a _________, which indicates how far the value is from the mean in standard deviation units, regardless of the unit of measurement. (hyphenated word)24A distribution is _________ ifthe left and right sides of the distribution match closely when folded vertically down the center.26A distribution is _________ ifmost of the data are on the rightand the extreme, less common scores are on the left. The mean will be to the left of the median. (4 wds)28The _________ measures thespread of a quantitative variablein a sample according to a formula. It is used for symmetricdistributions. (2 wds)DOWN1To denote both the mean of apopulation and the standard deviation of a population, we use _________ letters.2A distribution is _________ ifmost of the data are on the left and the extreme, less common scores are on the right. The mean will be to the right of the median. (4 wds)4A proportion is also called a_________ (2 wds)6Subtracting the differencebetween the 75th percentile andthe 25th percentile gives you the _________ range, a measure of spread for skewed distributions.8A two-way table shows therelationship between two _________ variables. Each cell shows the number of data cases that are in both the row and column categories.11To calculate the _________ of aquantitative variable, rank the data values in order from smallest to largest or vice versa,then find the middle value.12The mean of a population isreferred to as _________, whichis a Greek letter.17Compared to the mean, amedian is a _________ measure of a distribution’s center because extreme values do not change it very much.20A _________ shows the shapeof a distribution of a relatively small dataset. Data values that are the same are stacked on top of each other.21The _________ for detectingoutliers calculates 1.5 times the interquartile range, and an outlier is either less than the first quartile by that amount or larger than the third quartile by that amount. (2 wds)22A _________ is similar to a barchart but the bars touch each other and a numerical variable is shown on the horizontal axis.23In a set of data, the 25thpercentile and the 75th percentile are called the first and third _________, respectively.25If a distribution is approximatelybell-shaped, the 95% rule says that 95% of the data fall within _________ standard deviations from the mean, both above and below the mean.27The mean of a sample isreferred to as _________ (hyphenated word).
