Questions?

The fact that no one else is posting here makes me wonder if I am the only one struggling to grasp all of the material?

===========

Hello! Some level of struggle is a good thing as a way to stretch and grow, but too much can feel overwhelming. Sometimes it helps to break the overwhelming feeling down into smaller parts that you can handle one by one. Is there a particular question you have with which I can help you?

I am with you!

You are definitely not alone! I have struggled this week with the concept of Nominal, Ordinal, Interval and Ratio. Every time I was sure I had it correct....I did not! Very frustrating! Any one have some good suggestions on how to clearly choose the correct level of measurement?

I hear a request! Look for a special treatment of nominal, ordinal, interval and ratio levels of measurement, coming up in this week's lecture. I will be sure to tie it to the practical act of measurement.

Confused by these concepts

After re-reading the chapter several times and doing the Aplia problem set, I am still a bit muddy on accuracy, precision, reliability, and validity. Reading them individually I understand them, but when jumbled together where I need to apply them to a specific case I can never seem to differentiate between them (within their own sets, I mean).

=======

We'll review it in the next lecture, then!

During the aplia problem sets, I also had a very difficult time with Nominal, Ordinal, Interval, and Ratio measurements as well. I don't think the book does a very good job of explaining them in terms of the questions that they asked for the homework. Very frustrating.

====

I think it's fair to say both that A) the questions had accurate answers but B) required you to not just spit out definitions but think additionally about what those diferent kind of variables imply about measurement. Some of those questions were difficult!

-- Prof. Cook

I had posted a question several days ago about being able to differentiate between different paradigms, and am not finding it on here. Did it get deleted or disappear? Anyone else having trouble with this?

Hello there! I never saw that question, so haven't been able to respond to it. What is your concern? Also, remember that if you have trouble with the Padlet (some browsers are cranky) I invite you to pose a question by e-mail or in comments at the end of this lecture.

Best, Prof. Cook

I am struggling right along with all of you. I feel disorganized in my head trying to cram it all in and absorb it all. We have to keep trying.....no room for giving up! Between reading, questions, papers and group projects we all should be just fine :) Stay focused classmates.

Yep! Thinking about research is a new way of thinking, and new ways of thinking are challenging. It can sometimes feel frustrating, but if you persevere you will feel the benefit for your whole life -- because research is useful in all kinds of domains, and you'll end up using what you've learned even if you never become an official researcher.

-- Best, Prof. Cook

I too am having difficulty relating the concepts to the examples. So you are definitely not alone.
