Median and mode calculations can be performed on ordinal numbers. A factor is not directly observable; it is inferred from the variables.

One also should consider who the source is and whether the results may be biased. Essentially, the discriminant function problem is a one-way ANOVA problem in that one can determine whether multiple groups are significantly different from one another with respect to the mean of a particular variable.

Descriptive research is more rigid than exploratory research and seeks to describe users of a product, determine the proportion of the population that uses a product, or predict future demand for a product.

Non-sampling errors are those caused by faulty coding, untruthful responses, respondent fatigue, etc. It is a degree of uncertainty that we are willing to live with.

It also assumes normally distributed data; however, since this is a test on means the Central Limit Theorem holds as long as the sample size is not too small.

This is accounted for in confidence intervals, assuming a probability sampling method is used. Such samples often comprise friends and associates who bear some degree of resemblance in characteristics to those of the desired population. Factor analysis combines variables to create a smaller set of factors.

The level of indecisiveness that would exist without the information. In general, the value of information is determined by: Many studies take the analysis no further than cross tabulation. Finally, the data is tabulated to count the number of samples falling into various categories.

My guess is that sampling error would be the most commonly named type of survey error. For chi-square applied to cross-tabulated data, the number of degrees of freedom is equal to number of columns - 1 number of rows - 1 This is equal to the number of categories minus one.

A measurement may be reliable and not valid. Simple tabulations count the occurrences of each variable independently of the other variables. Sampling Plan The sampling frame is the pool from which the interviewees are chosen.

This F-test assumes that the group variances are approximately equal and that the observations are independent. Packaged goods manufacturers often conduct surveys of housewives, because they are easier to contact, and it is assumed they decide what is to be purchased and also do the actual purchasing.

There are two basic types of descriptive research: It often is used to analyze bivariate cross-tabulated data. As such, the attributes that create value cannot simply be deduced from common knowledge.
