How can a scientist reduce bias in a scientific investigation?
To reduce bias in a scientific investigation, a scientist can use randomization in sampling, blind studies, and double-blind studies. Randomization helps to minimize selection bias, while blind studies prevent participants from knowing which group they are in, reducing response bias. In double-blind studies, both the participants and the researchers are unaware of who is receiving the treatment, further minimizing bias.
What are the different types of bias in psychology?
Some types of bias in psychology include confirmation bias (favoring information that confirms existing beliefs), selection bias (nonrandom selection of participants), and observer bias (influencing research outcomes through expectations). It's important to be aware of these biases to ensure research findings are valid and reliable.

What is Selection Bias?
Selection bias is a kind of error that occurs when the researcher decides who is going to be studied. It is usually associated with research where the selection of participants isn’t random. It is sometimes referred to as the selection effect. It is the distortion of statistical analysis, resulting from the method of collecting samples. If the selection bias is not taken into account, then some conclusions of the study may not be accurate.The types of selection bias include:Sampling bias: It is a systematic error due to a non-random sample of a population causing some members of the population to be less likely to be included than others resulting in a biased sample.Time interval: A trial may be terminated early at an extreme value (often for ethical reasons), but the extreme value is likely to be reached by the variable with the largest variance, even if all variables have a similar mean.
