Generate EAN 13 In Java Using Barcode drawer for Java Control to generate, create EAN13 Supplement 5 image in Java applications. As the chart shows, the average of the squared differences is 717.43. To derive the standard deviation, simply find the square root of that value. The result is approximately 26.78. To interpret the standard deviation, remember that it is the average distance from the mean of each element in the sample. The standard deviation tells you how representative the mean is of the entire sample. For example, if you owned a candy bar factory and your plant foreman reported that the daily Painting Bar Code In Java Using Barcode generator for Java Control to generate, create bar code image in Java applications.

Here is an important rule of thumb: assuming that the data you are using conforms to a normal distribution, about 68 percent of the data will be within one standard deviation from the mean, and about 95 percent will be within two standard deviations.

One of the most common uses of statistical information is to make projections about the future. Even though past data does not necessarily predict future events, often such trend analysis is still useful. Perhaps the most widely used statistical tool for trend analysis is the regression equation. This is the equation of a straight line that best fits the data, and it is often referred to as the regression line, the least square line, or the line of best fit. Before describing how to find the line of best fit, recall that a line in twodimensional space has this equation: Y = a + bX Here, X is the independent variable, Y is the dependent variable, a is the Yintercept, and b is the slope of the line. Therefore, to find a line that best fits a set of values, you must determine the values of a and b. To find the regression equation, we will use the method of least squares. The general idea is to find the line that minimizes the sum of the squares of the deviations between the actual data and the line. To find this equation involves two steps. First, you compute b using the following formula: 8: Statistics, Graphing, and Java
Here, Mx is the mean of the X coordinate, and My is the mean of the Y coordinate. Having found b, a is computed by this formula: a = My bMx Given the regression equation, it is possible to plug in any value for X and find the projected value for Y. To understand the significance and value of the regression line, consider this example. Assume that a study tracked the average price of a share of stock for XYZ Inc. over a period of ten years. The data collected is shown here: Year 0 1 2 3 4 5 6 7 8 9 Price
68 75 74 80 81 85 82 87 91 94 The regression equation for this data is Y = 70.22 + 2.55 X The data and the regression line are shown in Figure 81. As the figure shows, the regression line is sloping upward (positively). This indicates an upward trend in stock prices. Notice also that the line closely fits the data. Using this line, one might predict that in year 11 the share price will increase to 98.27. (This is found by substituting 11 for X in the equation and solving for Y.) Of course, such a prediction is only that: a prediction. There is no guarantee that the prediction will come true!
