How can internal and external validity be increased in an experiment
According to Kelly “a test is valid if it measures what it claims to measure.”
A distinction can be made between both the (internal and external )validity. These types of validity are used to evaluate the validity of a research study.
Internal validity refers to whether the effects observed in a study are due to the manipulation of the independent variable and not some other factor.
or there is a causal relationship between the independent and dependent variable.
It can be improved by controlling extraneous variables, using standardized instructions, counter balancing, and eliminating demand characteristics and investigator effects.
External validity refers to the extent to which the results of a study can be generalized to other settings (ecological validity), other people (population validity) and over time (historical validity).
External validity can be improved by setting experiments in a more natural setting and using random sampling to select participants.
How can internal and external validity be increased in an experiment
Question 4 The difference between internal and external validity is best described as: Internal validity tells us if the inferences drawn from the study population are true of the study population whereas external validity tells us if the inferences drawn from the study population are true of the target population. Internal validity tells us if the inferences drawn from the population being studied apply to other populations whereas external validity tells us if the inferences drawn from the population being...
Give an explanation of a threat to internal validity and a threat to external validity in quantitative research. Next, explain a strategy to mitigate each of these threats. Then, identify a potential ethical issue in quantitative research and explain how it might influence design decisions. Finally, explain what it means for a research topic to be amenable to scientific study using a quantitative approach

Define the concepts internal and external validity. Discuss why we say that for some experiments an attempt at increasing one type tends to jeopardize the other type. research methods-psy230
16)Define internal validity: a. The extent to which we can draw causal conclusions about a study such as random and systematic error, confounding, and selection bias b. Exchangeability or how comparable the study group is to otherand explains generalizability or transportability 17. Define external validity: a.
