'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.

Answer:
The galaxy is moving closer to us
Explanation:
When there is a decrease in the wavelength of light which is being observed then it means that the object and observer are getting closer to each other.
When there is an increase in the wavelength of light which is being observed then it means that the object and observer are getting farther apart.
This phenomenon is called the Doppler effect.
Orange has shorter wavelength than red so the wavelength is getting shorter.
Hence, the galaxy is moving closer to us.
