From concept to instrument
1. Identify a concept/construct you can measure in your topic/study.
2. Define the concepts/construct (according to literature).
3. Provide an operational definition of the concept (what you understand by the concept or the definition of the concept in the context of your study).
4. Identify two variables that will help you measure the concepts/construct (see example in the slides).
5. Develop two items (questions) that will help you determine the respondents’ stance on a variable. There should be two items for every variable and the items should be in the form of a Likert-scale. (see the example below for one of the variables)
Student A B mean
S1 3 6
S2 2 5
S3 3 4
Mean score for all the respondents
6. Your instrument should also collect demographical information such as gender, age, race, education, salary, type of school, etc. (at least two demographical items that are relevant to what you are measuring, look at other quantitative instruments for examples).
A short discussion on the development of the instrument and the actual instrument used should be included in the assignment (you must describe how you developed the instrument).
Data collection and analysis
1. Distribute your instrument to at least 2 and a maximum of 4 participants.
2. You must then calculate percentages for each the demographical items.
3. The data from the Likert-scales must be presented in a table (see example). There should be two tables, one for each variable.
4. Calculate the mean for each participant’s stance on the variable. (you do not need to show the calculations, the final answer is sufficient).
5. From the mean scores of each participant, calculate the overall mean score for the respondents.
Report
1. Write a brief report (two pages max) and comment on the three demographic items data and the stance of the respondents on each variable using the overall mean score as a reference. Lastly, briefly comment on what the two variables suggest in terms of the construct you measured.
To recap, the following should be included in the assignment.
1. A coversheet with the title of your study.
2. A section on ‘from construct to variables’.
3. Description of the development of the instrument.
4. A copy of the instrument.
5. A table with the collected data and calculations.
6. A report explaining the meaning of the results and the implications thereof.
All of the elements stated above must be clearly indicated in your assignment.
