Independent variable
To achieve internal validity, a researcher must design and conduct experiments where only the independent variable can be the cause of the results.
<h3>What are internal and external validity?</h3>
The degree to which a study shows a reliable cause-and-effect relationship between a therapy and a result is known as internal validity. Internal validity also shows that a particular investigation enables the exclusion of competing hypotheses for a finding. Internal validity is not a binary term, either yes or no. Instead, we evaluate how confident we can be in a study's conclusions depending on whether it avoids pitfalls that could cast doubt on the results.
The term external validity describes how effectively the results of a study should be extrapolated to other contexts. In other words, the generalizability of the results is the subject of this form of validity. For instance, are the results generalizable to different populations, environments, circumstances, and eras? Transferability is a different word that describes external validity and a qualitative research design. Whether results apply other circumstances with similar characteristics is referred to as transferability.

Explanation:
Parliament is split into two houses: the House of Lords<span> and the </span>House of Commons<span>. The House of Commons is the lower house and is the more powerful. The House of Lords is the upper house and although it can vote to amend proposed laws, the House of Commons can usually vote to overrule its amendments. Although the House of Lords can introduce bills, most important laws are introduced in the House of Commons - and most of those are introduced by the government, which schedules the vast majority of parliamentary time in the Commons. Parliamentary time is essential for bills to be passed into law, because they must pass through a certain number of readings before becoming a law. Prior to introducing a bill, the government may run a public consultation to solicit feedback from the public and businesses, and often may have already introduced and discussed the policy in the </span>Queen's Speech<span>, an </span>election manifesto<span> or </span>party platform<span>.</span>
