Examples of quantitative variables include height and weight, while examples of qualitative variables include hair color, religion and gender. Quantitative variables are often represented in units of measurement, and qualitative variables are represented in non-numerical terms.
Know MoreThe difference between qualitative and quantitative variables lies in the way each are measured. Qualitative variables have no inherent order to them while quantitative variables are numbers that can be naturally ordered. Qualitative variables are often referred to as categorical variables because they can be placed into categories, such as male or female. According to OnlineStatBook, these variables can be ordinal, interval or ratio variables.
Learn more about StatisticsThe constant of variation is a number that relates two variables that are directly proportional to one another. The number represents a fixed ratio between the two variables, describing how they correspondingly increase or decrease. Constants of variation cannot be calculated for linear expressions that involve variables that are equal to multiple arithmetic terms. If the dependent variable does not equal zero when the independent variable equals zero, the two are not constantly varying.
Full Answer >A standardized regression coefficient removes the original unit of measurement for variables in a regression equation. These coefficients are standardized and converted to a scale from 0 to 1. Since the values are standardized, a researcher can more easily compare the effect sizes of variables measured on different scales.
Full Answer >Dichotomous variables are variables that have two levels. A very common example of a dichotomous variable is gender, which has two outcomes and is reported as male or female.
Full Answer >Quantitative data is any kind of data that can be measured numerically. For example, quantitative data is used to measure things precisely, such as the temperature, the amount of people in a crowd or the height of a structure. Although quantitative data usually involves numbers and equations, some data records actions, such as the frequency of human behavior.
