This PU565 Unit 1 discussion board post sorts three research questions about one gap and shows that only one of them needs interviews. Purdue Global PU 565, Qualitative and Quantitative Methods, opens the Master of Public Health (MPH) methods sequence by asking which design a question requires. Older adults in a composite county could buy hearing aids over the counter and mostly do not. The countable question, what share own and use one, is survey work. The question of what buying one would mean to somebody who has decided against it is interview work. The third, whether a reason given in interviews predicts non-use more widely, needs both in sequence. The post defends starting with the second.

Three Questions About the Same Gap, and Only One of Them Needs Interviews: A Unit 1 Discussion Board Post Sorting What to Ask About Older Adults in a Composite County Who Could Buy Hearing Aids and Do Not

PU565 · Unit 1 Discussion Board Post

Posted by [Student Name]

Culbreth County is composite; the regulatory change, the use figures and the research cited are real.

What this part is doingThe post sorts questions by the method each one requires, rather than arguing that one method is better, which is what the first unit of a methods course is asking for.

Initial Post

A gap between availability and use produces at least three different research questions, and the useful first move is to notice that they need different designs. Question one, countable: what proportion of Culbreth County adults over 60 with self-reported hearing difficulty own and use a hearing aid, and how does that differ by income and insurance? This is a survey question. It needs a sampling frame, a validated screen and a denominator, and it will produce a number a county commission can act on. National figures suggest the number will be low: among older adults with measured hearing loss, only about one in seven had used a hearing aid in the period before the over-the-counter rule (Chien & Lin, 2012). Question two, not countable: what does buying one mean to a person who has decided not to? This is an interview question, because the answer is a set of reasons, comparisons and fears that no fixed-response item will contain. The published work points this way: hearing loss carries a stigma that people manage by hiding the loss rather than by treating it, and the management strategies are the content a survey item flattens (Wallhagen, 2010). A survey can tell the county how many people are not wearing aids. It cannot tell the county what those people think wearing one would say about them. Question three, both: does a reason people give in interviews, such as price being a polite way to decline, predict non-use in the wider population? This one needs interviews first to find the candidate reason and a survey afterward to see how common it is, which is the sequence the course calls exploratory sequential. My own position for this term is that question two comes first here, because the county has already run a survey, the number is known to be low, and nobody can say why. Starting with the countable question would produce a more precise version of a figure we already have.

Reply to Classmate A

You argued for a survey first on cost grounds, and that is the strongest practical case. My hesitation is item content: writing response options for why somebody has not bought a device requires knowing what the plausible answers are, and if the options come from the literature rather than from this county, the survey will measure what researchers expect.

Reply to Classmate B

Your point that interviews cannot establish prevalence is one I accept entirely. I would only add that this is a reason to sequence the two rather than to choose between them, and that the sequencing decision is itself a methods question we will be asked to defend later in the course.

Reading the PU 565 Unit 1 instructions

Unit 1 usually asks students to turn one problem into research questions and match each to a method. Write three questions rather than one, and label each with the design it demands. Say what each design can deliver and what it cannot: a survey gives a proportion and no meaning, interviews give meaning and no denominator. Avoid arguing that one tradition is superior; the unit tests whether you can fit a method to a question. Where a question needs both, name the sequence and say which comes first. Support the claim that the gap exists with a published figure rather than an impression. Then take a position on where to start and give the reason. Two replies should press on a classmate's design logic.

Inside the PU565 Unit 1 example

The post here opens by observing that one gap yields three questions, each needing a different design, with a note in the margin on why sorting beats ranking. The countable question is specified with its sampling frame, screen and denominator, and a national use figure is cited to show what the answer will look like. The meaning question is given to interviews because fixed response options cannot hold reasons, comparisons and fears, and the stigma literature is cited for why. A highlighted line separates what a survey can tell a county from what it cannot. The third question is identified as exploratory sequential. The writer then argues for starting with interviews because the county already has the number, and the two replies take cost and prevalence objections.

Reading the PU565 Unit 1 grading rubric

Rubrics for this unit reward fit between question and method. Most points go to three questions each correctly matched to a design, with the limits of each design stated. Credit goes to recognizing that response options for a new survey have to come from somewhere, which is the strongest argument for interviews first. Points go to naming a sequence rather than treating mixed methods as a label. Citing a published figure for the size of the problem earns marks; asserting it does not. The position taken at the end is graded on whether the reason is specific to the case, so starting with interviews because the prevalence is already known scores well. Replies carry about a quarter of the grade and are marked on the challenge they raise.

Common PU565 Unit 1 mistakes, and how to avoid them

The commonest error here is a paradigm argument: a post defending qualitative or quantitative work in general while the prompt asks about one problem. Match methods to questions instead. The second is one question stretched across both designs, which hides the sorting the unit is testing. Third, do not claim interviews can establish how common something is, and do not claim a survey can explain a decision. Watch the sequencing claim too, since saying mixed methods without naming which strand runs first says nothing. And give the gap a published number. A post written to your own prompt and discipline can be drafted free within 24 to 48 hours.

PU565 Unit 1 questions, answered

Where can I find a free PU565 Unit 1 sample paper?

The post and both replies sit in full on this page, annotated where the reasoning turns.

How do you match a question to a method?

Ask what the answer would look like. A proportion needs a survey; a set of reasons and meanings needs interviews; a claim about both needs them in sequence.

Which strand should come first?

Whichever the other depends on. Here the survey needs response options that only interviews can supply, so interviews run first.

Can a survey measure meaning?

Only what its options allow. If the options come from published work rather than from the people being studied, the survey measures the researcher's expectations.
