## RRPQBBQ

How exactly do you score this Reactions to Research Participation Questionnaire Revised (RRPQ-R) form? I see some hints on the last page, but what steps would a researcher take to turn a stack of completed forms into data the proper way? I could take a guess but I'm curious to know the actual method. Google is seemingly empty of the answer. I do not think I have access to the sources on the last page.

## What Do I Do With All This Data?

I have a research project involving about ~90 subjects in two (self-selected) groups. I have collected a number of variables about these subjects (from public sources), and now I would like to do some statistical tests to say whether these variables are significantly correlated with membership in one group or the other. How do I do this? I have a basic knowledge of R and access to Stata 14. [more inside]

## Police Stops and/or Violent Interactions initiated by Burnt out Bulbs

Is there any research, discussions or statistics that link burnt out car bulbs to police stops, and then to either police shootings or anything related violent interactions between arrestees and police?

## Question about demographic research project

My question is about how to find someone who can appropriately choose a representative set of zip codes from a larger set.
How could I get someone to choose, in an intellectually defensible way, a list of 30 to 50 zip codes that essentially represent my entire state? In other words, how could I come up with a list of 30 to 50 zip codes that economically/demographically are a representative subset of the entire state? [more inside]

## What percentage of youth in foster care have parents who were in FC?

Research help: What percentage of youth in foster care are born to parents who were at one point in foster care of themselves?
I'm looking for information on the prevalence of intergenerational child abuse and experiences of foster care. In addition to the question above, I am also interested in what percentage of perpetrators of child abuse were victims of child abuse themselves. I've done some digging myself and haven't been able to find any data on this.

## The limits to bedbugs

What are the limits to bedbugs? Why isn't every hotel room infested given how tough they are claimed to be? Is there any evidence on the chances of taking bed bugs home from a hotel with you? Will the bedbug infestation rates go ever upwards? Why or why not? Interested in aggregated, rather than anecdotal evidence here. [more inside]

## How do I learn to read peer-reviewed studies comfortably?

I come from an engineering background rather than a research background, and I find myself lacking in vocabulary when it comes to understanding research papers, particularly when they start talking about ANOVA analyses, F(x) effect sizes and p values. I can skim through the results of a study and see that certain numbers are bigger than other numbers, but I don't really know how to tell whether what I'm seeing is significant. I'm guessing that I'm missing basic education in statistics. Can I fix this in a simple way?

## Help with Financial Research -- Statistics

I'm currently performing a mock research comparative analysis for a class. I'm researching the financials of 'our' metrics versus our highest competitors. One of the questions I'm attempting to answer asks if the variances (or standard deviations) of 'our' profit margins are statistically similar to the variances in profit margins of our competitors over a five year period. I have 11 companies representing the profit margins of our competitors, and of course the reports on our profit margins for these five years.
Now it's been a while since my last stats course... so I'm wondering, would I use an F or Levene's Test to answer this? Or am I completely off base... and should look to another form of analysis.

## Seeking advice/help about statistical tests of significance.

I have a wonderfully large dataset that I'm working with for a long-term project. I am analyzing a small section the dataset for my masters thesis. In meeting with my thesis advisor last week, she suggested I run some statistical tests of significance on the 4 tables I'm working with. She knows that I am yet to be versed in quantitative analysis methods (I've done solely qualitative work thus far) and that I'm under a massive time crunch to get this done. She suggested I seek help from others, as she doesn't want me to get bogged down with figuring out this step, and would rather I concentrate on analyzing the other aspects of this data. To this end, I'm wondering if somebody might be able to suggest the best type of test of significance to run, the easiest way to run it, and a good, simple resource for what the resultant values mean?

This is a delurk, so let met start by saying hello. I'm a biology student and I have recently started my first research internship.

Please recommend a good basic statistics manual, that will clear up the basics for me. I would prefer it uses R. [more inside]
