nobody would mistake those for being much more than a 4 banger adding machine. The TI scientifics have some crap screens by comparison. If I had to guess, most of the programming questions about the Casio comes from them having a "really nice" screen and students assume they carry the functionality of a CG50 graphing calculator or the HP programables. So HP has always been a horse of a different color. HP are more pocket computers than traditional calculators. It's a shame too because Sharp does make some really nice calculators, and well. Sharp and HP scientifics are the only real outliers. (Perform the following operation after completing the operations in Example 3.Casio and TI have been the two most common scientific calculators for a long time, probably 40 years. The corresponding x-value (two values, x 1 and x 2, in the case of quadratic regression) also can be calculated for a value of y in the regression formula.Įxample 4: To determine the estimate value for x when y = -130 in the regression formula produced by logarithmic regression of the data in Example 3. Logarithmic Regression Formula: y = -3857.984 + 2357.532ln xīased on the regression formula obtained by paired-variable statistical calculation, the estimated value of y can be calculated for a given x-value. Logarithmic Regression Correlation Coefficient: 0.998 Results: Linear Regression Correlation Coefficient: 0.923 Specify Fix 3 (three decimal places) for results. Results: Mean: 3, Population Standard Deviation: 1.154700538Įxample 3: To calculate the linear regression and logarithmic regression correlation coefficients for the following paired-variable data and determine the regression formula for the strongest correlation: ( x, y) = (20, 3150), (110, 7310), (200, 8800), (290, 9310). See "Calculating Estimated Values" for more information.Įxample 2: To input the single-variable data x = ), and calculate the mean and population standard deviation. They are commands of the type that take an argument immediately before them. X ˆ, x ˆ 1, x ˆ 2 and y ˆ are not variables. The content to the Statistics Menu depends on whether the currently selected statistical operation type uses a single variable or paired variables. While the Statistics Calculation Screen is on the display, press (STAT) to display the Statistics Menu. Pressing the key while the Statistics Editor is displayed switches to the Statistics Calculation Screen. The Statistics Calculation Screen is for performing statistical calculations with the data you input with the Statistics Editor. In the Statistics Editor, perform the following key operation: To delete all Statistics Editor contents: In the Statistics Editor, move the cursor to the location where you want to insert the line and then perform the following key operation: In the Statistics Editor, move the cursor to the line that you want to delete and then press. In the Statistics Editor, move the cursor to the cell that contains the data you want to change, input the new data, and then press. Pol, Rec, ÷R, and multi-statements also cannot be input with the Statistics Editor. The following operations are not supported by the Statistics Editor:, (M-), (STO). ▶Verifying the Authenticity of Your CalculatorĪll data currently input in the Statistics Editor is deleted whenever you exit the STAT Mode, switch between the single-variable and a paired-variable statistical calculation type, or change the Stat Format setting on the setup menu.Function Calculation Input Ranges and Precision.▶Calculation Ranges, Number of Digits, and Precision.▶Before Assuming Malfunction of the Calculator.▶Creating a Numerical Table from Two Functions (TABLE).▶Integer Part of a Value (Int) and Largest Integer that does not Exceed a Value (Intg).▶Greatest Common Divisor (GCD) and Least Common Multiple (LCM).▶Permutation ( nP r) and Combination ( nC r).▶Rectangular-Polar Coordinate Conversion.▶Power Functions and Power Root Functions.Answer Memory (Ans)/Previous Answer Memory (PreAns).▶Degree, Minute, Second (Sexagesimal) Calculations.▶Overwrite Input Mode (Linear Display only).▶Using Values and Expressions as Arguments (Natural Display only).(2nd edition / NATURAL-V.P.A.M.)
