Clinical Data Analysis on a Pocket Calculator
HK$ 518.00 HK$ 575.00
Kobo
In medical and health care the scientific method is little used, and statistical software programs are experienced as black box programs producing lots of p-values, but little answers to scientific questions. The pocket calculator analyses appears to be, particularly, appreciated, because they enable medical and health professionals and students for the first time to understand the scientific methods of statistical reasoning and hypothesis testing. So much so, that it can start something like a new dimension in their professional world. In addition, a number of statistical methods like power calculations and required sample size calculations can be performed more easily on a pocket calculator, than using a software program. Also, there are some specific advantages of the pocket calculator method. You better understand what you are doing. The pocket calculator works faster, because far less steps have to be taken, averages can be used. The current nonmathematical book is complementary to the nonmathematical "spss for Starters and 2nd Levelers" (Springer Heidelberg Germany 2015, from the same authors), and can very well be used as its daily companion.

5 Reasons Why People Still Use Traditional Calculators in Hong Kong

Today, most people are depending on computers for basic numerical problems. They open a calculator app when they just want to add small numbers. With this in mind, do traditional calculators still have a place in the market? The fact that there is a surging appeal for calculators and scientific calculators in Hong Kong means people still rely on them to perform various, significant tasks. Here are the reasons why a lot of people still use traditional calculators.

Aid in demonstrating concepts

What makes calculators a great tool in demonstrating numerical patterns and rules is their speed. It aids learners and especially teachers in expounding mathematical concepts faster. Regardless of what type of calculator they use, they can demonstrate various concepts through it. For teachers, they can better explain the patterns to repeating decimals and their connection to fractions to their students through a basic or any calculator. For students, they can fully interpret the changes in a graph by inputting different slope values with the help of a graphing or scientific calculator.

Accomplish real-world applications and problems

People who are employed in the field of science, technology, engineering, and mathematics will appreciate the use of a scientific calculator to solve work-related tasks. On the other hand, everyday people with mundane jobs figure out how much their hourly wages and mortgage payments through a calculator. Therefore, calculators can help you accomplish real-world applications and problems.

Assist in budget estimation

Right after you receive your salary, you make a pledge to yourself to budget accordingly. After a week, however, you find yourself facing an empty bank account. To avoid such situation, it’s recommended to take control of your spending with a budget plan. In your budget plan, you put entries such as monthly savings, monthly expenses, and annual expenses. Under each entry, say for monthly savings, you include fields like emergency funds, investment, and retirement. Then input your estimated amounts in all the fields. With the use of a financial calculator, you can determine the sum to figure out if you are under/over budget. So, say goodbye to an empty bank with a well-laid budget plan.

Helps in problem-solving

Calculators tremendously speed up the solving of physics, chemistry, and mathematics problems. Thus, they are an integral part of thinking and learning processes. However, in the case of students, some tend to depend on calculators too much and forget to learn basic mathematical skills. That’s why it’s still important for students to develop an understanding how to solve a math problem before relying on a calculator’s answer.

Keep financial transactions accurate

Printing calculators help maintain a business or company’s financial records accurate. They have a print feature which allows you to get a printout to check financial entry errors or a receipt to give to customers. Besides its printing ability, this type of calculator has unique keys that allow you to get a percentage, grand total, tax rate, and much more.
