SPSS: How To Enter, Code, And Analyze Multiple Choice Data

Summary

This video tutorial provides a comprehensive guide on entering multiple-choice item data into SPSS, emphasizing when to use multiple-choice questions versus Likert scale items. It illustrates the advantages of Likert scales for nuanced data collection and easier analysis. The presenter explains how to code and analyze single-choice and multiple-choice questions, offering practical examples and methods in SPSS. Additionally, the video discusses the use of multiple response sets for analysis, while highlighting that basic descriptive statistics can often suffice. The tutorial concludes with a fun pronunciation note on the Likert scale.

Takeaways

• 😀 Likert scales are often preferred over multiple-choice items for survey questions to enhance data granularity and accuracy.
• 😀 Changing survey phrasing from 'you' to 'I' can improve respondent engagement and clarity.
• 😀 Multiple-choice questions are appropriate when respondents must choose only one correct answer from a list.
• 😀 In SPSS, single-response multiple-choice items can be entered as nominal categorical variables with coded options.
• 😀 For questions allowing multiple selections, create a separate variable for each option, coding responses as 0 (not selected) or 1 (selected).
• 😀 Analyzing single-response questions can be done easily using descriptive frequency analysis in SPSS.
• 😀 Use the 'select cases' function in SPSS to filter and analyze specific response criteria for multiple-choice questions.
• 😀 Multiple response sets can facilitate complex analyses, but they are not mandatory for effective data analysis.
• 😀 Descriptive analyses can yield the same results as multiple response sets, making them a suitable choice for less experienced researchers.
• 😀 The correct pronunciation of 'Likert' honors the psychologist who developed this scale, emphasizing its proper usage.

Q & A

Why does the speaker suggest using Likert scale items instead of multiple-choice questions?

The speaker believes Likert scale items provide more gradations of response and greater accuracy in data collection, as well as simplifying the data entry process in SPSS.

How should the survey question about hotel booking channels be revised?

The question should be changed from 'When you book hotel rooms for holidays, which booking channels do you use?' to 'When I book hotel rooms for holidays, I tend to use the following booking channels,' with Likert scale options provided.

What coding method is recommended for a single-choice multiple-choice question in SPSS?

The speaker suggests coding the responses as a nominal categorical variable, assigning a unique number to each choice, such as 1 for 't test,' 2 for 'correlation,' etc.

What is the process for analyzing a question where respondents can select multiple answers?

Each potential answer should be coded as a separate variable with values of 0 (not selected) or 1 (selected). This allows for frequency analysis of how many respondents chose each option.

How can a researcher determine how many respondents gave the correct answer when multiple options are allowed?

The researcher can use the 'select cases' function in SPSS to filter responses, counting only those who selected all correct answers while excluding incorrect options.

What are multiple response sets in SPSS and when should they be used?

Multiple response sets allow researchers to analyze data where respondents can select multiple answers. They are useful for certain analyses but can often be substituted with standard descriptive statistics.

What analyses can be performed using multiple response sets in SPSS?

Researchers can perform frequencies, crosstabs, and additional statistics like t-tests and chi-squared tests using multiple response sets.

What is the main advantage of using descriptive analyses over multiple response sets for less experienced researchers?

Descriptive analyses are more straightforward and can achieve similar outcomes without the complexity of defining and using multiple response sets.

What does the speaker say about the correct pronunciation of 'Likert'?

The speaker clarifies that it should be pronounced 'Likert,' named after the psychologist who invented the scale.

What is the overall message of the video regarding survey design?

The video emphasizes the importance of careful question design and the benefits of using Likert scales for improved data quality and easier analysis in SPSS.
