'Although concrete operational thinkers might succeed on the balance-a-scale test of formal reasoning, they are less likely to do so because of their reliance on <u>trial and error</u>.
An operational definition is a definition that defines the precise way wherein a variable is measured. Giving the steps used in defining each variable allows others to evaluate and potentially mirror research take a look at.
Your operational definitions describe the variables you may use as indicators and the processes you will use to study or degree them. You need an operational definition due to the fact you can not measure something without one, regardless of how top your conceptual definition is probably.
An operational definition of a variable is the set of approaches used to measure or control it. a great operational definition is obviously sufficient so that an unbiased researcher ought to use the same technique (mirror the studies) and get identical outcomes.

Hello the answer for your question is immigration.
In completion of your question:
Calculate how many fish they can catch and how many huts they can build on their own in one year
Answer:
Bagley can catch 180 fish and build 90 huts.
Spano can catch 120 fish and build 40 huts
Explanation:
If Bagley spends all her time just catching fish in one year she can catch 180 fish (1800 hrs/10 hrs per fish), on the other hand if she spends all her time making huts she can make 90 huts (1800hrs/ 20 hrs per hut) in one year. If Spano spends all his time just catching fish in one year he can catch 120 fish. On the other hand, if he spends all his time making huts in one year he can make 40 huts.
The answers were each gotten by dividing the total number of hrs worked(1800) by each person's rate(such as bagley's 10hr/fish).
Answer: Positive reinforcement
Explanation:
Positive reinforcement refers to the state of providing the subject with a reward or something whenever they tend to perform action required, so that they can associate this action with reward and therefore tend to do often. This reward is known as reinforcing stimulus. This type of consequence tend to works because in this case the brain frequently connects the desired action with the reward, and thus subject tends to repeat this desired action in order to get the reward in the future.
