Understanding and working with the square root of 2 is critical to solving algebra and geometry problems. While you can always use a scientific calculator to do it, learning how to calculate the square root of 2 by hand can help when you don’t have one. In this post, we will go over the origins, …
The square root symbol isn’t a basic mathematical operator, which is why it isn’t on your keyboard, regardless of whether you’re using a Windows machine or a Mac. However, both of these operating systems make typing square root convenient and uncomplicated. In this post, we discuss the various ways you can type square root on …
It’s not uncommon for students to come across problems that require finding the square root of a number. While it’s easy to rely on a scientific calculator or a smartphone, learning how to find square root by hand can help understand the concept of square roots at a deeper level. There are a few different …
Calculating your courses grade is a useful skill to have. It will help you understand where you stand and how much progress you’ve made. Furthermore, it will help you determine how much more work you need to put in to earn the grade you want. A 1979 Harvard Business Study found that students that set …
Effective goal setting is one of the most powerful tools students use to ensure exam success. A 2015 Harvard Business study revealed that individuals with goals typically find ten times more success than people that don’t set any goals. Looking through the course of study and setting weekly study goals is an effective strategy to …
31% percent of surveyed students report that finals week is the most stressful time of the semester. However, the exams are rarely the last of a senior’s worries. To calculate your final grade, you will need to find the sum of your weighted grades. But it’s also possible to calculate the grade you require on …
Regardless of whether you’re looking to do plain arithmetic or want to solve complex science and engineering problems, you can rely on a scientific calculator to help. Getting acquainted with a scientific calculator’s functions can be challenging. Going through the manual is an option, but the instructions can sometimes seem needlessly convoluted. Here’s an easy …
Numbers can sometimes be too large or too small to be expressed normally. If you’re working on a problem involving the weight of the earth or the size of an atom, writing down or entering several zeroes in a calculator is inconvenient at best. Writing scientific notation is one of the easiest ways of expressing …
Electronic calculators have been around for centuries, and they’ve gotten progressively better. However, the first scientific calculator was invented and released to the masses only decades ago, in 1968. These devices are now a common sight in classrooms globally – but what exactly are they? Furthermore, how are they different from basic calculators? I’ve outlined …
If you’re taking an introductory statistics course, you’ll find out sooner than later that there’s no need for you to calculate standard deviation by hand all the time. While some statisticians-in-training get access to computers in class and use R or SAS to calculate standard deviation, many don’t have that luxury. But luckily, graphing calculators …
Comparing the means of two populations becomes easy with the help of two-sample t-tests. The results of these tests help determine if there is a big difference between the means of the samples. Furthermore, if the test outcome reports a large difference between the means, it means that the data samples are strong, and the …
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 …
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, …
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 …

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 …
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 to a few attributes. For example, you can use a t-test to …
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 – …
