If we are only interested in the summary statistics for the variable mpg and weight, type summarize mpg weight in the command window. This gives the following output: There are a variety of different types of samples in statistics. Each of these samples is named based upon how its members are obtained from the population. It is important to be able to distinguish between these different types of samples. Below is a list with brief description of some of the most common statistical samples.

Within multiple types of regression models, it is important to choose the best suited technique based on type of independent and dependent variables, dimensionality in the data and other essential characteristics of the data.

Types of variables Your variables may take several forms, and it will be important later that you are aware of, and understand, the nature of your variables.

An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

All researchers perform these descriptive statistics before beginning any type of data analysis. 2 One such restriction being the dependent variable in regression analysis. When working with statistics, itвЂ™s important to recognize the different types of data: numerical (discrete and continuous), categorical, and ordinal. Data are the actual pieces of information that you collect through your study.

Before you can understand these two major branches of statistics and the different type of procedures that fall under each, you first need to understand a few basics about variables. Variables . A . variable. is any entity that can take on different values. We can distinguish between two major types of variables: 1. Quantitative Variables вЂ“ numeric (e.g., test score, height, etc.) 2 The goal of statistics is to learn about populations. A statistical population is the set of all possible values for the variable. The statistical term population is different than the demographic term.

Probably the most common scale type is the ratio-scale. Observations of this type are on a scale that has a meaningful zero value but also have an equidistant measure (i.e., the difference between 10 and 20 is the same as the difference between 100 and 110). For example, a 10 year-old girl is twice as old as a 5 year-old girl. Since you can measure zero years, time is a ratio-scale variable Types of Variables. In the last section you reviewed qualitative and quantitative data. Surveys primarily collect quantitative data, so the rest of this module will focus on analyzing quantitative data.
