Discussion Overview

The discussion revolves around identifying potential confounding variables in an experiment designed to test insect preferences for dark versus bright environments. The scope includes experimental design and the implications of confounding variables on the validity of the results.

Discussion Character

  • Debate/contested

Main Points Raised

  • Post 1 presents a list of potential confounding variables and suggests A (varying humidity), E (type of light source), and F (varying temperature) as possible choices, while expressing uncertainty about their correctness.
  • Post 2 questions whether there is a single correct answer or multiple valid options, indicating that justifications could be made for all answer choices.
  • Post 3 and Post 4 emphasize the need for specific selections of three confounding variables from the provided list, with Post 4 highlighting the expectation for participants to engage in their own analysis rather than seeking direct answers.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which specific confounding variables to select, and there is disagreement on the interpretation of the task, with some seeking definitive answers while others encourage independent reasoning.

Contextual Notes

There is a lack of clarity on the definition of confounding variables as understood by participants, which may affect their ability to agree on the correct choices. The discussion also reflects varying interpretations of the task requirements.

Who May Find This Useful

Individuals interested in experimental design, particularly in biology or behavioral studies, may find the exploration of confounding variables relevant to their work.

biology urgent need help?

An experiment is set up to test whether a particular insect prefer a dark or a bright environment. A chamber with a gradient in light intensity from one end (dark) to the other (bright) has been made. The experimental hypothesis is:
“There will be a large difference between the number of insect in a dark side and the number in a bright side of the chamber.”
Which one could be the three confounding variables?

A - Varying humidity across the chamber
B - The orientation of the chamber
C - The age of the insects
D - The non-reflective material from which the chamber is made
E - The type of light source used
F - Varying temperature across the chamber

I was thinking A, E and F but there is something wrong even A,B and C is wrong
Any help would be appreciated. Thanks
can someone tell me which one is correct please

Is there one correct answer or are there multiple correct answers?

I think there are justifications for all the answer choices.

But first, what is a definition of a confounding variable, in your own words?
 
no i just need you to choose three confounding variables from the list please.
A confounding variable that should be kept constant/ controlled.
