Question

For each statement below write “primary” or “secondary” to describe that type of data.

i. An astronomer uses data from a science book to develop an explanation about the atmospheres on different planets.

ii. A student uses a table from a magazine to find out about moons around the planets.

iii. A teacher use a telescope to observe the crafters on the moon.

Which data are likely to be more reliable?

Explain your answer.

Answer 1

Step-by-step explanation:

All three sources of data (the science book, the magazine, and the telescope) are likely to be reliable, but to varying degrees.

i. The science book is likely to be a reliable source of information about the atmospheres on different planets, as it is likely to have been written by experts in the field and reviewed by other experts before being published. However, the information may not be as up-to-date as newer research.

ii. The magazine table is likely to be a reliable source of information about moons around the planets, as it is likely to have been written by experts in the field and reviewed by other experts before being published. However, the information may not be as detailed or in-depth as information from a scientific journal.

iii. The telescope observation is likely to be the most reliable source of information about the craters on the moon, as it provides direct observation of the phenomenon in question. However, it is important to note that the accuracy of the observations may depend on the quality of the telescope and the skill of the observer.

In general, information from scientific journals and textbooks written by experts in the field is generally considered more reliable than information from popular sources such as magazines, newspapers, or websites. Direct observations made using scientific instruments are generally considered to be the most reliable sources of information.
