What are the main types of validity?

Validity tells you how accurately a method measures what it was designed to measure. There are four main types of validity:

Construct validity: Does the test measure the construct it was designed to measure?
Face validity: Does the test appear to be suitable for its objectives?
Content validity: Does the test cover all relevant parts of the construct it aims to measure.
Criterion validity: Do the results accurately measure the concrete outcome they are designed to measure?

Frequently asked questions: Definitions

What does “let’s touch base” mean?: Let’s touch base is an expression used to suggest to someone that you touch base or briefly reconnect. It’s rarely used in formal or academic writing.
How do I pronounce “copacetic”?: Copacetic has four syllables. It’s pronounced with emphasis on the third syllable: [koh-pah-set-ik].
Is it “copacetic,” “copasetic,” or “copesetic”?: The standard spelling is copacetic. The variant spellings copasetic and copesetic are also listed as acceptable by the Merriam-Webster dictionary, but they’re less common.

The origin of the word is unclear (it’s thought to have originated as slang in the 20th century), which is why various spellings are deemed acceptable.
What does “please bear with me” mean?: Please bear with me is a more polite version of the expression bear with me, meaning “have patience with me.”

It’s typically used along with a conjunction (e.g., “while”), to explain why you’re asking for patience (e.g., “please bear with me while I try to find the correct file”).

Bear and bare are often confused, but in this case, ‘bear with me’ is the only correct spelling.
What is a synonym of “bear with me”?: Some synonyms for bear with me include:

What does “bare with me” mean?: “Bare with me” is a common misspelling of the phrase bear with me. While “bare” can be used as a verb meaning “uncover,” it doesn’t make sense in this phrase. The verb you need is “bear,” meaning “carry” or “endure.”

What are the two types of criterion validity?: Criterion validity evaluates how well a test measures the outcome it was designed to measure. An outcome can be, for example, the onset of a disease.

Criterion validity consists of two subtypes depending on the time at which the two measures (the criterion and your test) are obtained:

Concurrent validity is a validation strategy where the the scores of a test and the criterion are obtained at the same time.

Predictive validity is a validation strategy where the criterion variables are measured after the scores of the test.
What is the difference between convergent and concurrent validity?: Convergent validity shows how much a measure of one construct aligns with other measures of the same or related constructs.

On the other hand, concurrent validity is about how a measure matches up to some known criterion or gold standard, which can be another measure.

Although both types of validity are established by calculating the association or correlation between a test score and another variable, they represent distinct validation methods.

What does “mine as well” mean?: “Mine as well” is a common misspelling of the expression might as well.

This expression is used alone or as part of a sentence to indicate something that makes little difference either way or that there’s no reason not to do (e.g., “We might as well ask her”). You should write might as well, not “mine as well,” to express this meaning.

On some occasions, mine as well can be the right choice. “Mine” is the first-person possessive pronoun, indicating something belonging to the speaker. So you might use this phrase in an exchange like the following:

Person A: My legs are aching.

Person B: Mine as well. It was a long walk!
What does “you as well” mean?: You as well is a short phrase used in conversation to reflect whatever sentiment someone has just expressed to you back at them. It’s commonly used to respond to well wishes:

Person A: Have a great weekend!

Person B: You as well!

The phrase is made up of the second-person pronoun you and the phrase as well, which means “also” or “too.”

This phrase is synonymous with another phrase, you too. Both are only used conversationally, not in formal writing, because they’re not complete sentences and don’t make sense outside of a conversational context.
What does “as well” mean?: As well is a phrase used to mean “also” or “too.” It’s used to indicate something additional (e.g., “I’m going to the bank as well”).

It’s also used in different senses in various common phrases, such as “as well as,” “might as well,” “you as well,” and “just as well.”
Is it “aswell” or “as well”?: The correct spelling of the phrase meaning “also” or “too” is as well, with a space. “Aswell,” combining the two words into one, is considered a mistake by all major dictionaries.

In other phrases involving these words, too, they are always written as separate words: “as well as,” “might as well,” “just as well,” etc.
