Scaling Techniques

1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

He seeks to imply that judgement of a person should be based more on the content

1. A Likert scale (/ˈlɪkərt/[1]) is a psychometric scale commonly involved in research that employs questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term is often used interchangeably with rating scale, or more accurately the Likert-type scale. One of the most common scale types is a Likert scale. A Likert scale is commonly used to measure attitudes, knowledge, perceptions, values, and behavioral changes. A Likert-type scale involves a series of statements that respondents may choose from in order to rate their responses to evaluative questions

Develop at least four criteria, assign weights to each criterion, assign scores, and then calculate the weighted scores. Print the spreadsheet and bar chart with the results.

This concept is manifested in the inquiry as I will be reviewing the levels of rainfall and the sizes of stalactites from smallest to largest in Princess Margaret Rose Cave.

6) Prepare the survey for analysis. Set up the code sheet for this study. How will this study be set up to be tabulated by a statistical analysis program like SPSS?

Participants are instructed to answer questions with their current partner in mind. If the respondent does not currently have a partner, he or she should answer with the most recent partner in mind (Hendrick & Hendrick, 1986). Each item asks respondents to reply to questions on a five-point Likert-type response scale indicating level of agreement. Below is a sample item from the scale.

Offenders would be given a survey using the Likert scale (1-Poor, 2- Below Average, 3- Average, 4-Above average, and 5- Excellent) upon entering the program. Anything rated as a 3 or higher will be considered satisfactory. The survey is part of the intake and discharge process therefore mandatory to complete. This will guarantee a 100% participation rate. The offender would not be informed of the survey being part of an experiment to discourage any biases. The purpose of this survey is to gather offender’s experiences with staff, to see how offenders feel about the staff, what they think about staff attitudes, if they feel staff have an impact on their success in the program, and what do they think about the program.

Missing values were replaced by the average of all the other items in that scale for that individual respondent. Analyses were conducted to determine if the mean scores for individual items were significantly different (less than or greater) from zero, the neutral response value—signifying either statistically significant disagreement or agreement with an item, respectively. Next, a factor analysis was performed to determine if similar items clustered together into subscales. Descriptive statistics (means and standard deviations) and one sample, two-tailed t-tests were calculated for each resulting subscale (Butler, 2010).

To determine scores for qualitative responses such as interview questions, letters of recommendations and previous work experience questions, a scale would have to be created. To determine these scores, the answers would have to be looked at subjectively by the reviewer and given a number on a rating scale. Once the answers are given a numerical value, the total score can be compared to other applicants’ scores to determine who may be more valuable to the company.

It is a 21 item inventory rated on a five-point Likert scale ranging from zero (“not experienced”) to four (“great degree”). Participants are asked to describe a negative event that occurred in their life, and based on that event they answer the remaining questions. Questions include statements like, “I developed new interests” and “I discovered that I’m stronger than I thought I was.” It is comprised of five subscales including; new possibilities, relating to others, personal strength, spiritual change and appreciation of life (Tedeschi & Calhoun, 1996). Scoring is done by summing all of the questions: factors can be scored by summing the questions related to that factor. Higher scores indicate higher levels of posttraumatic

In order to get an accurate construct of measurement I have created a Likert-type scale. I have listed broad book genres that my student may encounter but not know a whole lot about. I will have her rate her interest in the genre from a 1 (Definitely Not Interested) to a 5 (Extremely Interested). This will give her plenty of room for her uncertanties to fall. I chose this type of measure because it will allow me the simplest way to see whether or not after my intervention her interests have changed.

Guttman scales employ a series of items to produce a scale score for respondents. [It] is designed to present respondents with a range of attitude choices that are increasingly difficult to agree with; that is, the items composing the scale range from those easy to agree with to those difficult to agree with. Respondents who agree with one of the “more difficult” attitude items will also generally agree with the “less difficult” ones

4. What measurement scales would you have used on the survey that was part of the in-restaurant product tests?

▪ This structure creates bias with the wording. A numerical scale from 1-5 or 1-7 would be ideal.
