The ability to generalize a study's results to different circumstances is known as external validity that suffers from 7 types of threats.
<h3>What are the threats to External Validity?</h3>
There are 7 major threats to external validity.
- The first threat is sampling bias, in which a sample is not representative of the population.
- The second threat is history, where an unrelated incident can affect the results.
- The third threat is observer bias, in which the traits or actions of the experimenter unintentionally affect the results, resulting in bias and other demand features.
- The fourth threat is the Hawthorne effect, which describes the propensity for individuals to alter their behaviour merely because they are aware that they are being observed.
- The fifth threat is the Testing Effect, in which the results are impacted by whether a test is administered before or after another.
- The sixth threat is the aptitude-treatment, which involves the interaction of individual and group factors to affect the dependent variable.
- The environment, time of day, location, researcher traits, and other variables that restrict the generalizability of the results are included in the seventh threat.

Answer: The value of u · d = 4
Explanation:
(2y -1) = 0 , 2y = 1 , y = 1/2 . u = 1/2

Substitute values for u·d 1/2 · 8 = 4
Answer:
O ovário é necessário na reprodução dentro do corpo, pois é responsável pela produção das células reprodutivas femininas ou óvulos.
Os testículos estão fora do corpo porque precisam ser mais frios que a temperatura dentro do corpo para produzir espermatozóides.
Explanation:
Isso ocorre porque os testículos funcionam melhor se forem mais frios que o interior do corpo. No tempo frio, os testículos se aproximam do corpo para se aquecer. Os ovários são mantidos por uma membrana ao lado do útero em cada lado da parte inferior do abdômen. O ovário é necessário na reprodução, pois é responsável pela produção de células reprodutivas femininas ou óvulos.
Boa sorte!
The answer is ...
150 this is how you find it
Ok so you 10,000 cars you divide that by 200
That is going to give you 50 groups of 200 and if each 200 cars have 3 cars with a defect you just do 50•3
Which is how you get 150 cats
Answer:
The answer is: the sentence is grammatically correct.
Why?
Mi mamá se sienta en el sofá / My mom sits on the couch/sofa.

Mi mamá/ My mom = subject
Se sienta / Sits = action (present)
en el sofá / on the couch/sofa = complement
