Question about Synergy Academic Kaleidagraph v3.6 for Mac (syn mac394) for Mac

Open Question

Can't get a scatter plot.

I'm new to Kaleidagraph and can't get a scatter plot to work on it. I put my data in the columns and go to Gallery->Linear->Scatter. I change column A to the X values and column B-F as the Y values. When I click on New Plot a message comes up saying "Text data columns can only be used as the independent plot variable." I have no idea what to do and would appreciate some help. Thanks, Mike.

Invalid dim when zoomstat


Invalid dimension is displayed if the two columns have unequal length (number of elements).
Try plotting the scatter plot first, then worry with the Zoom.

How to model real life data?


What is the question?
Put your calculator in STAT mode (2-var statistics or regression )
Enter your data in two lists, preferably sorted according to the x-value
Choose a regression model from the ones available and get the calculator to give you the best fit.
However to see which regression model best fits you data you need a graphing calculator to draw the scatter plot, then superpose on the scatter plot the curve of best fit given by the regression model.

Once you accept a model as the most suited one, you can use the equation of the curve to predict a y-value given an x-value (what ever REAL LIFE meaning they might have)

I can't see all of plotted points in scatter plot


Try to set the Zoom window to ZoomStat, this way the scatter plot will display all statistical points in the data set.

Ti 84 plus silver edition will not fit a linear model to plotted points. when I use the function vars>stat>EQ>RegEQ it transmits incomplete data in to Y=.


Your data must be in two lists L1 (for x-values), and L2 (for y-values). This is the default setting. Open the STAT utility, go to the regression models. Select your model then press ENTER. The command echoes on the main screen. For example let the regression be something called LinReg.
On the main screen you see LinReg
Complete the command line as follows
LinReg L1, L2, Y1, ENTER
You see the statistics including the regression equation.
If you go to Y= Editor you will see that Y1 contains the regression equation.
If you have already drawn the scatter plot for your data, pressing GRAPH will superpose the scatter plot and the regression curve., and you will be able to judge the goodness of the fit.

How do you make a residual plot? And I don't mean finding the residual line and plotting it in a regular scatter plot. I'm talking about a residual plot with a horizontal regression line at zero and the...


The simplest way would be to create a table where each x-value has a y-value that is the residual at the corresponding x. With a 2-list data set you can plot you residual plot.

I am trying to graph a least-squares line on my TI-84 Plus. I have the numbers correctly plugged into my Stat Edit tables, and I am able to access my linear equation, and the first time I entered my graph...


After you enter the data draw the SCATTER plot first.
When you perform the (linear) regression analysis LineReg, save the regression equation to a function, for example Y1
The syntax is
LineReg L1, L2, Y1 ENTER


From the Stat>CALC menu press LineReg
The command echoes on command line
Press [2nd][1] to enter the L1 list on command line
Press [,] to separate
Press [2nd] [2] to enter L2 on the command line
Press [,] the comma again
Press [VARS][>][Y-Vars][1~Function][1:Y1] [ENTER]
Press [GRAPH] to have the regression line equation drawn
on the same screen as the Scatter Plot you drew before.

I went to my table the other day, and accidentally deleted the Y column, do you know what I can do to get it back? thanks for your time.


The table corresponds to the values of a certain function you entered through the Y= Editor. Reenter the function as Y1= and the Y column will be regenerated.
If you are dealing with paired data ( statistical values) enter one variable in list L1 and the other in List L2 and use the statistical feature to draw a scatter plot or perform other data processing.

You might not see the scatter plot when you go to the graph because the boundaries are not set correctly. With the scatter plot turned on, go to "zoom" and then scroll down to "zoomStat" and hit enter. Try going to the graph again and see if the the scatter plot shows up. As for the the equation being slightly different than the examples, this is probably just the calculator rounding up the answers it gets. Good luck!

I assume you know how to enter data in your calculator. The keystrokes in the following pertain to TI92/92Plus/ Voyage 200 PLT. The main differences with the TI89/Ti89 Titanium is that the function keys F6,F7,F8 are not accessed directly but by the key sequences [2nd][F1], [2nd][F2], and [2nd][F3] respectively

1. CLEAN THE SLATE (so to speak) and ENTER DATA

In Home folder run F6: NewProb to reset the configuration.
Press Apps, and select 6: data/Matrix editor. Select a new data set
84e1901.jpg

Give it a name: here testing.

2133d3f.jpg

Press OK/ENTER, The data entry screen opens, enter your values.

When you finish press F2.PlotSetUp.

2. Statistical plot setup and scatter plot drawing

b142867.jpg.

Press F1:define to configure Plot1. Choose Scatter, then choose a mark for the data point. I select 5:Dot. and press [ENTER
0ee40be.jpg

Select the data column X=c1, Y=c2

65437f9.jpg

Press ENTER to save configuration. Press [CTRL] [GRAPH] On my TI92 the CTRL key is the [Diamond] key. On the following graph I changed the mark to a cross to see the data point better. I also played with the window dimension. You can also do that with ZoomStat. The graph remind me of a parabola (I know I chose the exact values)

3. STATISTICAL CALC. AND REGRESSION ANALYSES.

Now we have to find the equation that fits these data best.
You press APPS 6:Data/ Matrix editor but you select current to return to your data set. You are taken to the data entry editor (Figure 3 above). In that screen Press F5:Calc to edit the type of statistics you want

On first line select the type of regression model : Linear Regression, QuadReg quadratic regression (or anything else available) X is from column1, Y is from column 2. Store RegEQ The regression equation in say Y1(x)

7c9f572.jpg

Press ENTER to save to get the Regression Equation. Here it is
As you can see I cheated: a perfect parabola. R^2 =1.

And here the best fit represented on same graph as the statistical data

Usually you have to try different regression models, until you find the one that fits best the experimental data.

Graph plotting


Dear rachana, In MS word 2007 you can go to Insert then there are multiple graph patterns given in it, like column, pie and scatter chart. Just put your values in it and it click ok, you will get the chart on worksheet. Its that simple.

Please press fixya if that was helpful.
