1. The ethical cost/balance consideration for researchers before conducting a research are:
The four ways that researchers can humanely and ethically behave towards participants in their research projects are:
Informed consent are legal documents that ensures that participants are informed in understandable language about all the aspects of the research or study, and that participants agree to take part in the study or research without any coercion of any sort. Informed consent is to avoid any sort of malpractices or ethical violations during the study or research, and it safe guards the interests of the participants.
2. Control groups are essential because they help to focus on the independent variable that is being tested or studied. They helps to eliminate the effect of all other variables except the independent variable.
3. The "trade offs" that exist between internal and external validity are emperical certainity of the experiment, that is how efficiently and effectively does the study or research measures the desired aim or fulfills it's purpose that can be observed and measured, and that how applicable is the study under various contexts.
4. Manipulation check is a procedure to see independent variable differs on the dependent variable in different groups.
5. Ecological validity is how efficiently can a laboratory study or a test can bear resemblance to the real life situations. In other words how virtual conditions are close to real conditions. Example- Study conducted to measure the level of irritation due to excessive noise of traffic. In real life such conditions occur in the busiest roads and markets, these conditions are virtualized in the lab set up to measure the effect of noise on the level of irritation.
