TI Calculator Tutorials

For more information and tutorials, visit Student Lounge by Texas Instrument.

 

The TI-83/TI-84 series, Texas Instrument Graphing Calculators,
are capable of performing a vast number of operations.  This brief tutorial will highlight
only a few of the operations used in
Algebra and in Statistics.

΅        TI Calculator Use in Statistics      σ

 

This brief tutorial will highlight only a few of the operations in the statistical package, using the STAT button (Row 3, Column 3).

After pressing the STAT button, you have three options: EDIT, CALC, and TESTS.

 

  

 

            Description: Description: bame

 

EDIT – 1: Edit… allows the entry (in columns) and modifications of data to be used with CALC and TESTS features.

CALC – Allows calculations using data stored in the columns through the EDIT feature.
1:1-Var Stats – summary statistics for one set of raw data.

1:1-Var Stats – summary statistics for a frequency distribution.
2:2-Var Stats – summary statistics for two sets of data.
4:LinReg(ax+b) – Linear Regression line for y = ax + b using x as the predictor variable.

MATH function

4:! – Calculate the Factorial of a number.

 

Distribtutions (2ND VARS)

2:normalcdf – Calculate the Normal Probability that a ≤ x ≤ b (cumulative).

3:invnorm – Calculate the Value corresponding to cumulative area to its left.

 

A:binompdf – Calculate the Binomial Probability that x = a particular value.

B:binomcdf – Calculate the Binomial Probability that x ≤ a (cumulative).             

C:poissionpdf – Calculate the Poisson Probability that x = a particular value.

D:poissioncdf – Calculate the Poisson Probability that x ≤ a (cumulative).

 

TESTS – Allows hypothesis testing, develops confidence intervals, and creates ANOVA table values.
1:Z-Test – Test of hypothesis of mean for one large sample using raw data or summary data.
2:T-Test – Test of hypothesis of mean for one small sample using raw data or summary data.

 

2:T-Test – Matched Pairs: Test of hypothesis of mean for two samples using raw data or summary data.


3:2-SampZTest – Test of hypothesis of means for two large samples using raw data or summary data.
4:2-SampTTest – Test of hypothesis of means for two small samples using raw data or summary data.
5:1-PropZTest – Test of hypothesis of proportions for one large sample using summary data.
6:2-PropZTest – Test of hypothesis of proportions for two large samples using summary data.
7:ZInterval – Calculates the specified Confidence Interval of the mean for one large sample using raw data or summary data.
8:TInterval – Calculates the specified Confidence Interval of the mean for one small sample using raw data or summary data.
A:1-PropZInt – Calculates the specified Confidence Interval of the proportion for one large sample using summary data.
E:LinRegTTest – Calculates a- and b-values for y = a + bx and tests the significance of the Coefficient of Correlation using raw data.

Modeling – Statistical Modeling with TI-83 Calculator – linear, quadratic, and other regressions.

TI Calculator Use in Algebra   

 

This brief tutorial will highlight only a few of the operations used in algebra.

Find the zeros (roots or x-intercepts) of the function f(x) = 3x2 + 4x – 6.

 

  

 

The roots are approximately -2.230 and 0.897.
