Answer #1

It is True because reliability is measured in terms of correlation coefficient, i.e. reliability tells us about the spread of data or the variance of data and gives us specific information the data set.

It is clear that as the data values increases in a data set, more and more data values tends to locate at a single point, due to which variation decreases and provides us more reliable data set.

So, we can say that as we increase the number of measurements, variation in the data set reduces, which increases the reliability of the data.

Therefore, given statement is correct
