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