Is the TI 89 good for statistics?

The TI 89 is a hand held calculator that can be used for just about any math class, from algebra to complex analysis. But even if you aren’t a math major, it can be useful to help you calculate many stats problems easily. There are two types of TI 89: The TI 89 Titanium is packed with helpful and useful features.

Can TI 89 do standard deviation?

(You can use the Ti-89 to calculate the mean and standard deviation of either lists or matrices.

#### Do all functions have limits?

Some functions do not have any kind of limit as x tends to infinity. For example, consider the function f(x) = xsin x. This function does not get close to any particular real number as x gets large, because we can always choose a value of x to make f(x) larger than any number we choose.

How to calculate the correlation coefficient on TI-89 calculator?

How to Calculate the Correlation Coefficient on Ti-89 Calculator Press the APPS button Select stats/list editor Type the independent variable data into list1. The independent variable causes the dependent variable to change. Type the dependent variable data into list2. Select F4: Calc Select 3: Regressions Select 2: Lin Reg (ax +b)

Where to type dependent variable in TI-89 calculator?

Type the dependent variable data into list2. Where it says “X list”, type in list1 (with no spaces). You do this because you stored the independent variable in list 1, and the x-axis (the bottom horizontal line of a graph) always shows the independent variable. Where it says “Y list”, type in list2 (no spaces).

## What does R stand for in linear correlation?

Note that correlation reflects the noisiness and direction of a linear relationship (top row), but not the slope of that relationship (middle), nor many aspects of nonlinear relationships (bottom).” Look first at r, the coefficient of linear correlation . r can range from −1 to +1 and measures the strength of the association between x and y .
