What is a trend line

Answer 1

A trend line is a straight line that is drawn on a graph to represent the general direction and pattern of a data series. It helps to identify and understand the trend or movement of a variable over a period of time. Trend lines are commonly used in various fields, including finance, economics, statistics, and data analysis. They can be used to analyze and forecast data, identify patterns, and make predictions about future values based on historical trends. Trend lines can be upward (positive), downward (negative), or flat (horizontal), depending on the direction of the data series.
