Validity

Question 4

If the coefficient alpha for a stress scale was computed to be .80, the scale would be which of the following?

Colaizzi

Van Kaam

Giorgi

Husserl

Question 25

Which of the following statements is true?

Content analysis is the analytic method used in phenomenologic studies.

CAQDAS is available for coding, organizing, and retrieving qualitative data.

Narrative materials tend to be linear, which simplifies the coding process.

Qualitative researchers typically develop a category scheme before they collect their data.

Question 26

Phenomenology most fundamentally involves a search for which of the following?

Common patterns shared by particular instances
