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.

After pressing the STAT button, you have three options: EDIT, CALC, and TESTS.   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. Y=  Graphing functions; Solving equations Entering and graphing a function MATH function 4:! – Calculate the Factorial of a number. Some Matrix Operations using TI-83/84 Calculators Graphing Parametric Equations using TI-83/84 Calculators CALC – Allows calculations of algebra functions and statistics using data stored in the columns through the EDIT feature. EDIT – 1: Edit… allows the entry (in columns) and modifications of data to be used with Modeling. 5:intersect – Find the intersection of two graphs such as Y1 =  and Y2 = Inequality Graph – graphing inequality with one variable using TI calculate Modeling – Statistical Modeling with TI-83 Calculator – linear, quadratic, and other regressions. E:LinRegTTest – Calculates a- and b-values for y = a + bx and tests the significance of the Coefficient of Correlation using raw data.
