The way that the field experiment similar to a lab experiment is that both allows for the manipulation of an independent variable.
<h3>What is the field experiment?</h3>
This is the term that is used to refer to the experiment that is conducted by the researcher who goes into the environment to get the cause and the effects of what they are researching on.

nervousness.
Explanation:
The answer is "nervousness".
Though Bella is studying hard and is studying diligently for the last two months for the exam, Bella is not confident on herself that she remembers everything what she have studied and is nervous.

Answer:
The sociometric/peer acceptance category of controversial relates to children who are noticed by peers and are liked by a quite a few children and disliked by quite a few others.
Explanation:
<u>A sociometric status is a measurement that shows how liked or disliked children are by their peers.</u> It can be divided into five categories: popular, rejected, neglected, average, or controversial. <u>The controversial category is the one that answers our question. It refers to children who are liked by quite a few children and disliked by quite a few others. Children who belong to this category have qualities that can be perceived as good or bad by others.</u> For instance, they tend to be prone to anger, and may seem a bit snobbish. On the other hand, they can also be sociable, cooperative, and good at sports.
An urn includes white and black balls. if a random sample of length is chosen, the probability that it consists of exactly white balls: 
Sample area = M + N
we are choosing r balls from the pattern space
So the possibility of having the exactly white ball is ok which means the okay of decided on balls is black
So the probability is 
Probability is honestly how probable something is to manifest. each time we are unsure about the final results of an event, we will talk about the probabilities of certain results—how in all likelihood they're. The analysis of activities governed via probability is referred to as information.
Probability is the branch of mathematics concerning numerical descriptions of ways in all likelihood an occasion is to occur, or how in all likelihood it's miles that a proposition is proper. The opportunity of an occasion is more than a few between zero and 1, in which, more or less talking, 0 suggests the impossibility of the occasion and 1 shows reality.
Probability = the number of methods of achieving achievement. the full number of feasible effects. for instance, the possibility of flipping a coin and it being heads is ½, due to the fact there may be 1 manner of getting a head and the whole wide variety of viable consequences is two (a head or tail).
