U1L2: Data

Histograms, box-plots, and measures of central tendency

frequency an interval made up of data values in that interval
frequency table a table that groups a set of data values into intervals and shows the frequency for each interval
histogram a graph that can display data from a frequency table
cumulative frequency table a table that shows the number of data values that lie in or below a given interval
symmetric describes a graph consisting of two parts that are congruent to each other
skewed left(negative)/skewed right (positive) distributions with fewer observations on the left/right
bell-shaped when the graph of a data set creates a symmetric bell-shape
uniform when the observations in a set of data are equally spread across the range of the distribution
unimodal/bimodal distributions with one clear peak/two clear peaks
gap areas of a distribution where there are no observations
outlier an extreme value that differs greatly from the other observations
measures of central tendency measurements that summarize a data set
mean the sum of the data values divided by the total number of data values (the average)
median the middle value in a data set when the values are arranged in order
mode the data item that occurs most times
measure of dispersion a measurement that describes how spread out the values in a data set are
range the difference between the greatest and least values
quartiles values that divide into four equal parts
interquartile range the difference between the third and first quartiles
