Rounding vs Estimating Rounding and estimating are two methods used for approximating a number for easier usage, when very large numbers are found. Both rounding and estimating are usually performed mentally, without the aid of writing or using a calculator. The goal of rounding and estimating is to make the numbers simpler to perform […]

## Difference Between Classification and Tabulation

Classification vs Tabulation Both classification and tabulation are methods of summarizing data in statistics, which makes further analysis of data to draw inferences from the data. In this article, we will discuss in detail the two methods of summarizing the data and distinguish between classification and tabulation of data. What is Classification of Data? […]

## Difference Between Ascending and Descending

Ascending vs Descending Ascending and descending are two terms that are taught in elementary math classes to students. In fact, these happen to be the very first of the math concepts that are taught to students. In general, ascending is a word that refers to the act of climbing up (stairs or a peak), […]

## Difference Between Fundamental and Derived Quantities

Fundamental vs Derived Quantities Experimentation is a core aspect of physics and other physical sciences. Theories and other hypothesis are verified and established as scientific truth by means of experiments conducted. Measurements are an integral part of experiments, where the magnitudes of and the relations amongst different physical quantities are used to verify the […]

## Difference Between Circumference, Diameter and Radius

Circumference vs Diameter vs Radius Radius, diameter, and circumference are measurements of three important properties of a circle. Diameter and Radius A circle is defined as the locus of a point at a constant distance from a fixed point on a two dimensional plane. The fixed point is known as the center. The constant […]

## Difference Between Pyramid and Prism

Prism vs Pyramid Prisms and Pyramids are solid (three dimensional) geometrical objects. Both prisms and pyramids are polyhedrons; solid objects with polygonal shape surfaces. They are not often found in nature, but most useful in mathematics, science and technology. Prism The prism is a polyhedron; it is a solid object consisting of two congruent (similar […]

## Difference Between Parametric and Non Parametric

Parametric vs Non Parametric Statistics is one branch of studies which allows us to understand population dynamics by using samples drawn from a certain population of interest. It is essential that these samples be random. Many formulae are created with incorporation of mathematics, to take inferences about population parameters. Naturally any population may have […]

## Difference Between Stratified Sampling and Cluster Sampling

Stratified Sampling vs Cluster Sampling In statistics, especially when conducting surveys, it is important to obtain an unbiased sample, so the result and predictions made concerning the population are more accurate. But, in the simple random sampling, the possibility exists to select the members of the sample that is biased; in other words, it […]

## Difference Between Radian and Degree

Radian vs Degree Degrees and radians are units of angular measurement. Both are commonly used in practice, in fields such as mathematics, physics, engineering, and many other applied sciences. Degree has a history running back to ancient Babylonian history while radian is a relatively modern mathematical concept introduced in 1714 by Roger Cotes. Degree […]

## Difference Between Positive Correlation and Negative Correlation

Positive Correlation vs Negative Correlation Correlation is a measure of the strength of the relationship between two variables. The correlation coefficient quantifies the degree of change of one variable based on the change of the other variable. In statistics, correlation is connected to the concept of dependence, which is the statistical relationship between two […]
