How do you calculated slope without invertlevel?
Slope of a straight line = (y1-y2)/(x1-x2)
How do you calculate a straight line in statistics?
The method used to calculated the best straight line through a set of data is called linear regression. It is also called the least squares method. I've included two links. I know the wikipedia link is a bit complicated. The slope and intercept are calculated based on "minimum least squares." If I draw a line through the set if points, for every x value in the data set I will have a y value and a predicted y value (y-hat) based on the straight line. The error (E) is this case is the predicted y minus the actual y. Linear regression finds the slope and intercept of the equation that minimizes the sum of the square of the errors. Mathematically this is stated as: Min z = sum (yi - y-hat)^2 To hand calculate a linear regression line wold take some time. The second link that I've included shows how to calculated this using excel.
What does the straight line with a line above it mean?
In mathematical notation, a straight line with a line above it typically represents a specific type of mean or average, such as the arithmetic mean. In statistics, it can also denote a line segment or a bar over a variable to indicate its mean value. In some contexts, it may represent a repeating decimal. The exact meaning can vary based on the specific area of study or usage.
Do line segments have to be straight?
Yes. If it is not straight, then it is not a line.
How do you explain straight line graphs?
it just a straight line
