Answer 2

The most commonly used mathematical method for measuring the trend is (c) the Method of least squares.

• Trend measurement allows forecasting of an anticipated end result of the statistics or observations.
• Various techniques used for trend forecasting are the least square method, the straight-line method, and the free-hand curve method.
• The least-square method is the manner of locating the best-fitting curve or line of an exceptional match for data points by lowering the sum of the squares of the offsets of the points from the curve.
• During the manner of locating the relation among variables, the trend of final results is expected quantitatively. This manner is called regression analysis.
