The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.

Why does slope matter?

I am assume that you mean the slope of a graph. We find the local maximum and minimum of a graph by comparing the slope (the tangent to the curve) at each point. When the graph is reaching either a maximum or minimum, the slope becomes zero. This finding-the-zero-slope task is normally done with computer programming or Excel. Another use is that the change in slope indicates a change in the rate. Let us say we are plotting the water level in a river to see when the dam will be breached. If the slope keeps increasing, you can predict, at the present rate of change, when the water will overflow. If the slope of water keeps decreasing, you can predict, at the same rate, when do we run out of water. Using the slope for prediction needs to be done carefully -- how much do you trust the data and how long can you project into the future without being unrealistic. The chartists use the slope to predict the trend of stock prices. The government uses the slopes of different sets of data to plan policies. And so on. ==========================

What shows a correlation which may be positive or negative between two sets of data?

I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.


What is trend analysis and importance of trend analysis?

Trend analysis is the study of data wherein data is looked at closely to see if any patterns exist within the set. It is important because it could clue someone in on what is happening within their data. For instance, trend analysis is used to determine the most popular products in a store at a given time.
