Q

What are 4 strategies for generating hypotheses? And why do they mean?

A

Introspection –> Engage in self-observation — Ask yourself “What would I do?” “How would I feel?” or “What would I
think?”

Find the exception to the rule -> Crafting hypotheses about outcomes in the opposite direction of prior research has the potential to
provide new insights into a phenomenon.

A matter of degree —>
Try to think about your variables in terms of amounts, such as quantity, intensity, strength, volume,
number, force, persistence, and effort of IV

Change the directionality –>
There is not a set direction of how one thing influences another

Debrief –> provide participants with true purpose of study
Dehoax –> describe the deception and why it was necessary

Desensitize –> remove side effect

133
Q

models are the intermediate between theory and data

163
Q

179
Q

What is continuous interval data?

A

Ranked and evenly spaced data

Test scores (e.g., IQ or exams)

No absolute zero –> zero doesn’t mean a complete absence

The difference between any two adjacent temperatures is the same: one degree. But zero degrees is defined differently depending on the scale – it doesn’t mean an absolute absence of temperature.
The same is true for test scores and personality inventories. A zero on a test is arbitrary; it does not mean that the test-taker has an absolute lack of the trait being measured.

180
Q

What is continuous ratio data?

A

ranked, evenly spaced, and has a natural zero.

A true zero means there is an absence of the variable of interest. I

(covers breadth) → does it measure all aspects of hapiness or just one aspect

193
Q

What is convergent and discriminant validity

A

(is/isnt related)Discirminant: Shows you that two tests that are not supposed to be related are, in fact, unrelated. It evaluates whether measures of different constructs are distinct from one another.

Convergent: : shows you that two tests that are supposed to be related to each other are, in fact, related. Convergent validity assesses whether different measures that are supposed to be measuring the same underlying construct actually converge or correlate with each other.

A

Hypothesis testing
results are held to the highest standards
Data-independent (the outcome or decision is not influenced by the specific data being analyzed.)
Minimizes false positives
P-value retain diagnostic value
may be generalized to larger population

type of research approach aimed at testing specific hypotheses or theories using predefined hypotheses, variables, and methods.

Example: An economist conducts a study to investigate the impact of minimum wage policies on employment levels in different industries.

279
Q

What is exploratory research?

A

Hypothesis generating
Results deserve to be replicated and confirmed
Data-dependent

Minimizes false negatives ignorer to find unexpected discoveries

P-value lose diagnostic value

can’t be generalized to a larger population

more open-ended and seeks to generate new hypotheses or insights.

Ex: A social scientist conducts interviews and focus groups with teenagers to explore their attitudes and behaviors towards social media usage. The researcher does not start with specific hypotheses but aims to uncover patterns, themes, and insights that may inform future research questions or hypotheses.

280
Q

What do you submit for preregistration?

A

Analysis plan, hypothesis, design and procedure and planned sample and exclusion criteria

281
Q

What are registered reports?

A

When there are 2 rounds of peer review. One after you design the study and before you collect data and one after you write the report.

282
Q

Questions asked during peer review stage 1 in RR

A

Are the hypotheses all founded
Are the methods and proposed analyses feasible and sufficiently detailed

Is the study well powered

283
Q

Questions asked during peer review stage 2 in RR

A

Did the authors follow the approved protocol
Are the conclusions justified by data

284
Q

How can open science be liberating and foster creativity?

A

enables us to explore data transparently and comfortably

Rewards quality, which is under our control, rather than outcomes, which are not

Reduce the choke hold of needing to find “positive results for career advancement

285
Q

What makes RR reports good in regards to what they publish?

A

Articles are published whether then hypothesis is supported or not
whether p<0.05 or not
Whether results are novel or not

286
Q

What is generalizability?

A

the extent to which findings, results, or conclusions drawn from a specific study can be applied or generalized to a broader population, context,

287
Q

What is a constraints on generisability statement and what should it consider?

A

Participants → different people

Materials / Stimuli → does the risk taking task actually generalize to the real world

Procedures → talk about limitations

Historical / Temporal Specificity → how specific is the historical context → does covid research translate to stress research at other times (in prison)

Situation Sampled (not included in the paper)

288
