Observations

Explanation – Observations are made through human senses, measuring devices or instruments. Even while carrying out an experiment, we observe the changes happening during and after the experiment and accordingly the data are collected and the result is inferred.

Example – If it is very windy outside and the clouds are dark then we predict that it might rain. However, if we see it is raining then it is our observation.
