DESCR Inferential Statistics

Easily solve descriptive or inferential statistical calculations with our application, which allows you to perform calculations for inferential and descriptive statistics quickly and easily. We can solve calculations for variance, one or two-sample hypothesis testing, proportions, distribution tables, and any other indicators of inferential and descriptive statistics. Our application provides you with the necessary tools to make statistical calculations more efficient.

Topics covered include:

- Calculations of population or sample variance and standard deviation.

- One-sample hypothesis testing for population mean.

- Two-sample hypothesis testing for population means.

- One-sample hypothesis testing for population proportion.

- Two-sample hypothesis testing for population proportions.

- Normal distribution Z-table to calculate alpha and p-value.

- Student's t-distribution table to calculate alpha and p-value.

- Fisher's F-distribution table to calculate alpha and p-value.

- Discrete binomial and Poisson distributions.

- Continuous uniform distribution.

- Simple sampling for finite or infinite populations.

- Stratified sampling for population means (Neyman and optimal).

- Cluster sampling.

- One-way analysis of variance.

- Simple linear regression.

- Statistics for grouped interval data.

- Statistics for ungrouped and grouped point data.
