3. More types of variables and dataIndependent and Dependent VariablesMany statistical experiments explore relationships between variables. In some cases, one variable (known as independent) predicts another variable(known as dependent). In some cases, several independent variables predict a single dependent variable. In graphical terms, Independent variablesare plotted on the X-axis while dependent variables are on the Y-axis.Relationships Between VariablesIf two variables are distributed consistently, we conclude that a relationship exists. However, you must be careful how you characterize thisrelationship. Are the variables merely correlated, or is there a causal relationship (that is, one variable causes the other)?Check Your UnderstandingIdentify whether each of the following variables is a nominal, ordinal, discrete, or continuous variable.Variable of interestEye colorAverage speed drivenSale price of a carNumber of cars soldSurvey response (Strongly disagree, Disagree, Neutral, Agree, Strongly agree)Distance traveledLength of a phone callAnnual incomeQualitativeNominal OrdinalOOOOOOOOOOOOOOOQuantitativeDiscrete ContinuousOOOOOOGrade It NowOOOOOSave & Continue
