When given a set of data where the independent variable is time, it is possible to use statistical techniques to find a line (or curve) of best fit. One of the ways to do this is to minimise the square of the the differences between the actual values which are observed and the values that are predicted by such a curve (fitted values). The slope of this line or of the tangent to the curve at any point, is the least squares trend.
A statistical explanation of the theory or the calculations required are too much for the pathetic browser that we are required to use.

Which step comes last when using the divide-center method to find the trend line on a scatterplot?
The last step in using the divide-center method to find the trend line on a scatterplot is to calculate the slope and y-intercept of the line based on the calculated averages of the divided segments. After determining the means of the x and y values for the segments, you use these averages to derive the linear equation that represents the trend line. Finally, the trend line is plotted on the scatterplot to visually represent the relationship between the variables.
What should you use to find the equation for a line of fit for a scatter plot?
Least squares regression is one of several statistical techniques that could be applied.

it is a description of the Slope of the line with respect to the two variables you are plotting. In Statistics, you may be plotting AGE versus Car Mileage and a line drawn through the data is the Trend Line.http://wiki.answers.com/What_does_a_trend_mean_on_a_line_graph#ixzz18qYakrsc
How do you find the range of a bar graph?
Subtract the greatest range by the least and you have your answer.
How do you find equation of trend line?
To find the equation of a trend line, you typically use a method called least squares regression. First, collect your data points and plot them on a scatter plot. Then, apply the least squares formula to calculate the slope and y-intercept of the line that best fits the data. The resulting equation is usually expressed in the form (y = mx + b), where (m) is the slope and (b) is the y-intercept.
How can you use a scatter plot to find an equation of a trend line?
By finding the line of best fit and using the straight line equation formula.
What is the first step in solving this equation by completing the square?
The first step would be to find the equation that you are trying to solve!

How can you find an equation for a trend line?
There are numerous ways to do this. I think the easiest is to put the data in excel and have excel show the trend line, equation, andcorrelation coefficient. Excel gives you several options to choose for the trend line analysis. The other way is if it is a linear relationship, you can do the linear regression analysis following the steps listed in the related link. If you are not familiar with regression analysis, it may not be easy for you to follow.
What is an equation that contains at least one variable?
An equation that contains at least one variable is (2x + 5 = 15). In this equation, (x) is the variable, and the equation states that when you multiply (x) by 2 and add 5, the result equals 15. Solving for (x) will allow you to find its value.
