Question

Mark the correct statement: All of these statements are correct The measured values are collectively called data O Random errors tend to cancel themselves out over a large number of measurements O It is possible that each time we take a data point we make a random error

Answer 1

It is true that random error tend to cancel if we take large number of measurment. Since these random errors are on both sides (positive or negative) so when we have large number of samples they tend to cancel out

Yes it is quite a possibility that every time we take a measurement we make some random error. That is why we get a distribution of data instead of a single point when we measure same thing again and again.

So

All these statements are correct
