## When To Use Paired t-Test

A t–Test in statistics is a hypothesis testing method that facilitates the comparison of the results (more specifically, the means) of two scenarios.  These tests are termed “t-Tests” because they boil the sample data down to one number called the t-value. Paired t-Tests are a variation of regular t-Tests, and these tests only work on …

## How To Interpret T-Test Results

In statistics, hypothesis tests enable you to gauge whether the results of a study, experiment, or survey have produced meaningful results. T-tests are of different types and can be used under different circumstances. If you need to compare a mean to a hypothesized value, you can use a simple one-sample T-test. On the other hand, …

## How To Do Fractions On A Scientific Calculator

While scientific calculators are designed to help solve complex engineering, physics, math, and chemistry problems, like business calculators, they display fractions as decimals by default. This means if you enter a fraction like ¾ on the calculator, the display will read 0.75. However, most scientific calculators have a feature that enables you to display fractions …

## How To Use Log On Scientific Calculator

Logarithms are easy to understand. They are functions that help you determine what exponents must be multiplied into a specific number. As you move on to learn advanced math, you will need to use scientific calculators to calculate log values quickly.  These calculators are very different from basic and business calculators and come loaded with …

## How To Calculate P Value From T-Test By Hand

T-tests are some of the most commonly applied statistical tests in all of math. If you pick up any research paper, chances are, you will see p-values in it.  Learning to do T-tests by hand and finding the p-value (with the help of a T-distribution table) will help you understand how hypothesis testing works much …

## What is a T-Test?

A T-Test is a hypothesis test that we use in statistics to compare two data sets’ respective means. It is a kind of inferential statistics. It concludes if there is a significant difference between the two groups’ means, which otherwise could be related in a few attributes. For example, you can use a t-test to …

## When to Use T-Test vs. Z-Test

A hypothesis is an assumption of a scenario that is rejected or accepted based on the test result. There are two kinds of hypothesis testing method: Parametric test: variables are measured on an interval scale Non-parametric test: variables are measured on an ordinal scale There are two types of tests in a parametric test – …
