Exam 15: Data Processing and Fundamental Data Analysis

The mode of a distribution of responses is the middle response in the distribution,meaning half of the responses are larger and half of the responses are smaller than the mode.

Error checking routines and marginal reports are two ways of machine cleaning the data.

Describe the five steps in the analysis process.

The mode is always equal to the mean.

Using the data below compare and contrast male and female soft drink consumption.You will need to compute the proper measure of central tendency and dispersion to support your answer.

If an interviewer did not properly follow skip patterns specified in a questionnaire,the ______________ step in data analysis would reveal the problem.

A common way of setting up cross-tabulation is to use columns to represent factors such as demographics and lifestyle characteristics,which are expected to be predictors of the state of mind,behavior,or intentions data,shown as rows of the table.

Finding the value that occurs most frequently determines the__________.

Which of the following is not a measure of dispersion?

Error checking routines and marginal reports are part of which of the following processes?

Pie charts are useful for depicting changes over time.

Given the following crosstabulation output,answer the questions below: a.1)What percentage of males did not attend at least one movie at a movie theatre in the last year? b.2)What percent of all respondents were female and attended at least one movie at a movie theatre? c.3)What percent of all respondents that did not go to at least one movie at a movie theatre in the last year were female?

____________ is the process of grouping and assigning numeric codes to the various responses to a question.

Open-ended questions are often necessary even in surveys whose major objective is to produce quantitative data.Given the open-ended responses below,how would you summarize them for analytical purposes? QUESTION: How do you think the taste of Pepsi compares with Coca Cola? Responses: The taste of Pepsi was 1) Better 2) Sweeter 3) Too sweet 4) Not as refreshing 5) More refreshing 6) Sweeter is better 7) Bolder taste 8) They taste about the same 9) I don't know 10) I don't have any idea 11) I don't drink soft drinks 12) Soft drinks are not good for you 13) Sweeter is better 14) Not a refreshing as Coca Cola 15) Coca Cola has always been my favorite brand

The first step in the data analysis process is coding.

The TextSmart module of SPSS is not an example of the new breed of automated coding systems.

Validation of data is an attempt to check the accuracy of the work done by _______

The process of "validating" online surveys is quite different.

The quality control aspect of the data analysis procedure refers to:

A variable with a large standard deviation would have a large variance as well.
