The following graphs show an outlier and a violation of the assumption that the residuals are constant. Plot with outlier. One of the points is much larger than all of the other points. Therefore, the point is an outlier. If there are too many outliers, the model may not be acceptable. You should try to identify the cause of any outlier. \(y \geq \frac{-3}{2}x + 6\) becomes \(y = \frac{-3}{2}x + 6\). Now plot that line as shown: Since this is a case where the inequality is true for y values greater than or equal to something, we have shaded the area above the line. All points on or ABOVE this graph line will satisfy our inequality.

The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular [latex]x[/latex] value. The [latex]y[/latex] value of a point where a vertical line intersects a graph represents an output for that input [latex]x[/latex] value. Interpolate the data using spline and plot the results. Specify the second input with two extra values [0 y 0] to signify that the endpoint slopes are both zero. Use ppval to evaluate the spline fit over 101 points in the interpolation interval. Dec 14, 2011 · The position versus time graph for such a system will be an upward-opening parabola like that shown below. The vertex of this parabola is a point where the slope of the graph goes to zero. A point of zero slope in a position vs. time graph implies that the velocity goes to zero at that time.

Let’s first graph the points we have, and we can see that the ellipse is (barely!) vertical.We know that the endpoints \((–1,–6)\) and \((–1,2\)) are in fact vertices, and not co-vertices (since the focus is on the same line). The center is halfway between the two vertices, so it is \((-1,-2)\). To help with the predictions you can draw a line, called a best-fit line that passes close to most of the data points. Approximately half of the data points should be below the line and half of the points above the line. If the data points come close to the best-fit line then the correlation is said to be strong. If the normal distribution is a good fit for the data, the points form an approximately straight line and fall along the fitted line that is located between the confidence bounds. Departures from this straight line indicate departures from normality. If the p-value is greater than 0.05, you can assume that the data follow the normal distribution.
