When pressed , a CHOOSE box is displayed with a number of problem areas within statistics where the HP 50g can be applied.  \nThe first choice deals with calculating many values related to the statistics of a single variable, such as the average, standard deviation and others. The second choice deals with placing data within bins or classes and is useful when dealing with frequency distributions or when there is a need to summarize data within a histogram. The third choice , Fit Data... is what we will use to compute trend lines. The fourth choice allows for the computation of summary statistics from a data set , such as the sum of all X values, the sum of all the Y values squared , and others. The fifth choice allows for the evaluation of many different hypothesis tests and the sixth choice allows for the construction of confidence intervals around a sample mean.  \nTo develop a linear regression cost estimation equation, press the ˜key until the third choice [Fit Data.. is](Fit Data.. is) highlighted and press the F key to register the choice of \\#\\#OK\\#\\# shown above the Fkey at the right side of the display. The `key can also be used to make selections from a CHOOSE box and will be used below. Alternatively, since the Fit Data.. choice is the third item in the list, the 3key can be pressed to immediately choose this function.  \nThe screen displayed allows for the entry of the existing data for the estimation of linear regression equations. The ∑DAT field at the top of the screen is where a matrix containing the statistics data is entered.  \nWhen the cursor is on this field , press the A key at the top left of the keyboard to register the choice of \\#EDIT!!. When pressed , the MatrixWriter is started to allow for the entry of the statistical data as shown in the screen below.  \nIn many ways, this screen works like any spreadsheet. Enter numbers and they will go in the highlighted cell. The menu labels at the lower left corner of the screen , !!!GO􀀡!! and !!GO°!, determine the direction the cursor moves after a data point has been entered , either right to the next column or down to the next row. In this example, the selection is to move right after each data point has been entered. This is indicated by the square present next to the !!!GO􀀡!! menu label. To change the way the cursor will move, press the menu label for the direction desired and the square in the menu label will change accordingly. If a column is too small to show the data entered, the !!!WID􀀡!! and !!±WID!!! menu keys may be used to expand or shrink the area displayed for each column.  \nEnter the first X data value by keying in the numbers and pressing the `key. The cursor will move to the right into the second column where the first Y data value should be keyed with the `key pressed to accept this value. At this point, the cursor will be in column 3. Use the ˜and škeys to move back to the first column and enter the second X data value. Continue entering the pairs of numbers in columns 1 and 2 until all have been entered. Since the variable for ∑DAT will hold its contents from one  \nhp calculators -2- HP 50g Cost Estimation using Linear Regression  \nhp calculators  \n HP 50g Cost Estimation using Linear Regression   \ncalculation to the next, be alert to extra rows of data that may exist below the last row entered for the current calculation.
