Validity, Reliability and Sampling
Do you think that the Project Implicit test is valid?
Yes. The test has both face and content validity. The questions measure what the test intends. Also, the survey consists of items that cover most aspects of the construct being measured.
Is the Project Implicit test really exploring your implicit bias, or do you think it has limitations?
Yes. The test has a wide range of questions which cover most aspects of the survey’s intentions. The questions bring out every aspect of implicit biases, therefore, making it a proper study.
What about the method they use of clicking letters on the keyboard to determine internal bias?
The method used is simple and fast. Having to click only two keys, E and I, makes the entire process quick and enjoyable. It also manages to capture the attention of the person taking the test.
What type of measurement error could emerge through the method used in the Project Implicit test?
Systematic error may have emerged through this method, which was used in the test. Systematic errors may occur because of poor observation by the person taking the test. Environmental conditions such as unreliable internet service may also be a cause of the error.
Do you believe that the Project Implicit test is reliable?
No. Retaking the test at a later time may produce different results from the first. The test reliability can be estimated by test-retest reliability. It can be done by giving the survey to a group of respondents and, at a later time, administering the test with the same group. The results at the two-time points are then compared.
Would you likely get the same results if you took the Project Implicit test 10 times in a row?
No. Repeating the test numerous times may become tiresome and annoying because it involves the same questions. Also, the style of taking the test is identical hence making taking the survey more than once dull. It is also quite long.
How would we test the validity or reliability of the Project Implicit test?
The Implicit test’s validity would be measured by using another survey in the form of a field test to inspect how well a given measure relates to one or more external criteria. On the other hand, reliability can be measured by providing the survey to a group of respondents and, at a later time, administering the test with the same group. The results at the two-time points are then compared.
How could we improve the Project Implicit test to be more valid or reliable?
The first step is involving expert to provide reviews about the test. It will help highlight any problems the questions and scales may have about its scope. Also, the pictures used should be colored to improve visibility hence reduce errors.
Now, think about other surveys, quizzes, or tests that you have taken in the past. For example, a survey about your political views.
Was that survey valid?
Yes. The questions measured what the survey intended hence making it a valid study. Most aspects of the construct being measured were covered.
Did that survey explore the actual topic of the survey?
Yes. The survey fully covered all aspects of the topic. It had a wide range of questions regarding the topic in which the respondent had to choose YES or NO from the choices provided.
Was this survey reliable?
Yes. Since the survey had only two choices to choose from, it proved to be reliable because of its simplicity. Retaking the test numerous times would produce the same results.
What is the importance of having a reliable and valid measurement?
Validity and reliability ensure that found results are accurately applied and interpreted.
