No. I believe TI83+ and TI84 do use an operating system.
Yes. The TI83 has several applications that can be downloaded onto the TI83, mainly those made by Texas Instruments. Also, you can write your own software.
To create a residual plot on a Casio graphing calculator, first enter your data points into a list. Then, use the regression function to calculate the best-fit line for your data. After obtaining the regression equation, compute the residuals by subtracting the predicted values from the actual values and store them in a new list. Finally, plot the residuals against the independent variable using the graphing feature of the calculator.
There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.
To determine if the line of best fit is appropriate for the data, examine the residual plot for randomness. If the residuals are randomly scattered around the horizontal axis without any discernible pattern, it suggests that the linear model is suitable. Conversely, if the residuals display a pattern (such as a curve), it indicates that a linear model may not be the best fit for the data.
No, it really depends on the college. Some colleges don't allow any calculators for their math classes. Everything that can be done on a TI83 can be done with the human brain, so some professors make tests with easier computations so that you don't have to use a TI83
Press "ALPHA", then press "."
An analysis of the residuals can be used to check that the modelling assumptions are appropriate.
the sum of the residuals is always 0(zero) because its how far they are away from the LSRL. that's what makes them residuals in the first place :P
how much in residuals is jason alexander receiving from seinfeld
Some TI83's can be set up differently, so it is highly recommendable to read the user guide for the TI83 in question. The user would need to go into the VarStat option and enter all the appropriate fields to have the calculator bring in the appropriate variables and totals.
The TI-83 calculator uses 4 AAA batteries.
