4.What types of statistical analyses are typically used with survey data? Why?

Solution

There are three major categories.

1 )Descriptive statistics are numbers that are used to summarize and describe information. The word \"information\" refers to the dats that has been collected from an experiment, a survey, a historical record, etc. (By the way, \"data\" is plural.

Descriptive statistics are the basic measures used to describe survey data. They consist of summary descriptions of single variables and the associated survey sample. Examples of descriptive statistics for survey data include frequency and percentage response distributions, measures of central tendency (which include the mean, median and mode), and dispersion measures such as the range and standard deviation, which describe how close the values or responses are to central tendencies.

Inferential statistics offer more powerful analyses to be performed on your online web survey data. As the names suggests, this branch of statistics is concerned with making larger inferences about social phenomena. This can include associations between variables, how well your sample represents a larger population, and cause-and-effect relationships. Some examples of inferential statistics commonly used in survey data analysis are t-tests that compare group averages, analyses of variance, correlation and regression, and advanced techniques such as factor analysis, cluster analysis and multidimensional modeling procedures.

2)Parametric statistics is a branch of statistics which assumes that the data have come from a type of probability distribution and makes inferences about the parameters of the distribution. Most well-known elementary statistical methods are parametric.

3) Nonparametric statistics are statistics not based on parameterized families of probability distributions. They include both descriptive and inferential statistics. The typical parameters are the mean, variance, etc.
