Step 1
According to the question, we have to provide the information related to the most accurate statement regarding inference. Let us have a look at this and find the best suitable option from the above mentioned.
Step 2
Inference can be explained in this way – when we draw a conclusion by depending upon certain evidence, facts, and aspects that are available at this point of time. We can also figure out the inferences based on an experience. So, in simple words, we can say that it is a conclusion or opinion that is formed because of known facts or evidence. So, if we check the statements given above –
The first option is – A inference can be used along with observation to form a conclusion, which is the meaning or definition of inference. So, it is correct.
The second option is inference should never be used to gain knowledge, this is not true because with the help of this we get a clear idea of any evidence or facts and thus helps to increase our knowledge.
The third option is inference makes no assumptions, this is also not true because it is not possible to draw a conclusion without the help of assumptions in the case of inference.
The fourth option is inference should not be used in scientific work, this is also not true because inference has a large scope in science like in ancient times prediction.
The final option is inference is a type of observation this is not completely true as inference main function is to draw the conclusion.
Step 3
So, the statement that is most accurate is – A. inference can be used along with observations to form conclusions.
