pie chartcategorical data, ?r chartcategorical data; displays counts or frequencies for a category dot plotquantitative data, data is represented by a single point stem plotsquantitative data, shows distribution while representing specific data points box plotsquantitative data, can be used to compare data sets, each part is 25% of data histogramsquantitative data, display frequencies or counts quantitative datanumerical data, it makes sense for it to be added categorical datadata that consists of names, labels, or other nonnumerical values relative frequencya way to approximate a percentage by dividing the number of times an event occurred by the number of trials frequency distributiona record of the number of times data occurs within a certain category outliersan observation point (number) that is distant from the other observations of a data set

centera measure of central tendency that is used to describe an entire set of data with one value that represents the middle or center of the distribution (mean, median, mode) intervala set of numbers between two specified values check sheeta table that allows data to be collected by marking how often an event has occurred in a certain interval symmetric distributionsthe left half of a data set being roughly identical to the right half bell curvenormal distribution, results from graphing frequency versus distribution for a trait that varies continuously in a population skewed-righttype of data distribution where frequency starts small, increases, then gradually decreases again skewed-leftdistribution where data starts small and consistently increases before dropping off again u-shapeddistribution where data in the middle is lower than the data on the left or right uniformdistribution where all data is virtually the same

bimodaldata set with only two peaks multimodaldata set with multiple peaks statisticsthe collection and classification of data that are in the form of numbers reliable datadata that is consistent and repeatable valid datadata resulting from a test that accurately measures what it was intended to measure five number summarylists the minimum, first quartile, median, third quartile, and maximum in a data set quartilesdivides data into four equally sized groups interquartile rangedifference between the third quartile and the first quartile normal symmetric (measures of center and spread) mean; standard deviation skewed (measures of center and spread)median; range or interquartile range explanatory variable (independent variable)the cause of some result response variable (dependent variable)the affected or changed variable C→Cboth variables are categorical; displayed in a two way frequency table (contingency table) C→Qcategorical and quantitative; displayed in with side by side box plots
