bivariate statistical analysis - -Tests of hypotheses involving two variables. -class coding - -Coding that assigns numbers to categories in an arbitrary way merely as a means of identifying some characteristic. -codes - -Rules for interpreting, classifying, and recording data in the coding process; also, the actual numerical or other character symbols assigned to raw data. -coding - -The process of assigning a numerical score or other character symbol to previously edited data. -contingency table - -A data matrix that displays the frequency of some combination of possible responses to multiple variables; cross-tabulation results. -cross-tabulation - -The appropriate technique for addressing research questions involving relationships among multiple less than interval variables; results in a combined frequency table displaying one variable in rows and another in columns. -data transformation - -Process of changing the data from their original form to a format suitable for performing a data analysis addressing research objectives. -descriptive analysis - -The elementary transformation of raw data in a way that describes the basic characteristics such as central tendency, distribution, and variability. -dummy coding - -Numeric "1" or "0" coding where each number represents an alternate response such as "female" or "male." -effects coding - -An alternative to dummy coding using the values of -1 and 1 to represent two categories of responses.
