Explanation of Solution
Trend analysis is an important component or technique of Time Series, which uses past data to predict the future. It indicates the change in a variable over a given time period. It may be stationary, positive, or negative.
A positive trend is one in which a rise in one set of data results in an increase in the other set. And a negative trend is one in which a rise in one set of data results in a decrease in the other set.
