There are many methods, though the most popular is the method of least squares. This method minimises the sum of the squares of the vertical distances between each point and the corresponding point on the line.

When finding the slope of the trend line what does the slope mean about the data of the scatterplot?
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.
What is a time series in maths?
Time series is a method of using past data to predict future values. It is based on the assumption that there is an undelying trend to the data. To predict future values, we use the concept of moving averages.
What graphs are used in finding trends in data?
Scatter graphs are best. Line graphs are OK if the trend is linear but not much good if the trend is non-linear.
What are the disadvantages and disadvantages of least square method?
The disadvantages are that the calculations required are not simple and that the method assumes that the same linear relationship is applicable across the whole data range. And these are the disadvantages of the least squares method.
Why isnt it necessary for all of the data points to be on the drawn line of the graph?
The line of a graph is quite often used to indicate the average of various data points that fall both above and below the line. Very jagged lines get smoothed out, but the trend is the same.
What is a graph that shows the relationships between two sets of data?
