Because the sum of the deviations would, by definition, always be zero. So there is nothing to be minimised to improve the fit.

The disadvantages are that the calculations required are not simple and that the method assumes that the same linear relationship is applicable across the whole data range. And these are the disadvantages of the least squares method.

High sensetivity to outliers (i.e. Extreme observation)

A scatter diagram will give a quick but rough extimate of the trend line - especially if there is a lot of variation about the trend. The least squares method will be more accurate.

The square root of 196 is 14, no matter what method you use. If you work a math problem two different ways and get different answers, then at least one of them is wrong, and there's a good chance that both of them are.

Square roots are computed using the Babylonian method, calculators, Newton's method, or the Rough estimation method. * * * * * Or the Newton-Raphson method.

26 is the least integer whose square root is an irrational number between 5 and 7. This is apparent as the square root of the previous integer (25) is a rational number and since the division method for calculating the square root produces a decimal that continues infinitely without repetition.

The square root of 366,025 is 605. I don't know the division method, but that doesn't matter. The result is the same no matter what method you use to find it. If you work the same problem by two different methods and get two different answers, then at least one of them is wrong, and there's a good chance that they both are.
