If your Stats teacher is asking you to compute things such as:
Lower & Upper Inner (Outer) Fence
5 Number Summary
and you have a Tinspire CX CAS then head over to
Statistics Made Easy which actually makes Statistics a lot easier: Finding Mean, Median, Mode, Standard Deviation, Variance, Fences, IQR, Statistical Tests, Distributions, Confidence Intervals and a whole lot more …
Using Statistics Made Easy at https://www.tinspireapps.com/?a=SPME and menu item
Linear Regression you just type in the given x and y values. Next the linear regression is computed for you along with the Correlation Coefficient and the Coefficient of Determination.
All is well!
You helped me over text a week ago!
Everything works like a charm.
Just purchased the statistics app and just activated
That works as well.
Watch this Youtube Video for an overview and examples at
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
