xBookUtils.terms['apparent limits'] = 'apparent limits what seem to be the upper and lower bounds of an interval in a grouped frequency distribution.';
xBookUtils.terms['bar graph'] = 'bar graph a graph of a frequency distribution for discrete data that uses the heights of bars to indicate frequency; the bars do not touch.';
xBookUtils.terms['continuous numbers'] = 'continuous numbers answer the question “how much” and can have “in-between” values; the specificity of the number, the number of decimal places reported, depends on the precision of the measuring instrument.';
xBookUtils.terms['cumulative frequency'] = 'cumulative frequency a count of how often a given value, or a lower value, occurs in a set of data.';
xBookUtils.terms['cumulative percentage'] = 'cumulative percentage cumulative frequency expressed as a percentage of the number of cases in the data set.';
xBookUtils.terms['discrete numbers'] = 'discrete numbers answer the question “how many,” take whole number values, and have no “in-between” values.';
xBookUtils.terms['frequency distribution'] = 'frequency distribution a tally of how often different values of a variable occur in a set of data.';
xBookUtils.terms['frequency polygon'] = 'frequency polygon a frequency distribution for continuous data, displayed in graphical format, using a line connecting dots, above interval midpoints, that indicate frequency.';
xBookUtils.terms['grouped frequency distribution'] = 'grouped frequency distribution a count of how often the values of a variable, grouped into intervals, occur in a set of data.';
xBookUtils.terms['histogram'] = 'histogram a frequency distribution for continuous data, displayed in graph form, using the heights of bars to indicate frequency; the bars touch each other.';
xBookUtils.terms['kurtosis'] = 'kurtosis how peaked or flat a frequency distribution is.';
xBookUtils.terms['midpoint'] = 'midpoint the middle of an interval in a grouped frequency distribution.';
xBookUtils.terms['modality'] = 'modality the number of peaks that exist in a frequency distribution.';
xBookUtils.terms['negative skew'] = 'negative skew an asymmetrical frequency distribution in which the tail extends to the left, in the direction of lower scores.';
xBookUtils.terms['positive skew'] = 'positive skew an asymmetrical frequency distribution in which the tail extends to the right, in the direction of higher scores.';
xBookUtils.terms['real limits'] = 'real limits what are really the upper and lower bounds of a single continuous number or of an interval in a grouped frequency distribution.';
xBookUtils.terms['stem-and-leaf display'] = 'stem-and-leaf display a data summary technique that combines features of a table and a graph.';
xBookUtils.terms['skewness'] = 'skewness deviation from symmetry in a frequency distribution, which means the left and right sides of the distribution are not mirror images of each other.';
xBookUtils.terms['ungrouped frequency distribution'] = 'ungrouped frequency distribution a count of how often each individual value of a variable occurs in a set of data.';
