## Step by Step Statistics app for the Ti-Nspire CX available now Watch this Youtube Video for an overview and examples at https://youtu.be/1HKbdf4zvvM

Shows Step by Step solutions for most Statistics and Probability topics.

• Step by Step Confidence Intervals for mean, proportion, 2 means, 2 proportions, variance, slope, etc.
• Compute Sample Sizes for Confidence Intervals.
• Step by Step Tests of Significance (Z-Tests, T-Tests, ChiSquare Goodness of Fit and Independence tests, 2-sample T tests, 2 proportion Z tests, for Variance, etc)
• Step by Step Regression.
• Read about how Confidence Intervals behave.
• Read about Significant Tests: Type 1 Error, Type 2 Error, Power of a Test.
• Much easier handling than other Statistics packages: Choose to enter Data or Statistic values. Select Significant/Confidence Levels easily.
• Distributions: compute probabilities, etc.
• Includes Binomial, Geometric, Normal, Student-t, Exponential, Poisson, Multinomial, Hypergeometric, F-, Chi-Square and more Distributions.
• Probability Checker for independent events, disjoint events. Also solves P(A or B)=P(A)+P(B)-P(A and B) for the unknown.
• Regressions: Linear , Quadratic, Cubic, Quartic, Sinusoidal, Logarithmic, Exponential, Power, MedMed
• Step by Step Derive the Coefficients for a Linear Regression Line, the Coefficient of Determination and the Correlation Coefficient.
• Also: Z-score Solver, Random Number Generator, etc
• 1 or 2 variable stats on mean, mode, median, standard deviation, variance, range
