In mathematics, you might have encountered the terms expression and equation very often. As both combines number and/or variables, people often misunderstood an expression for an equation. However, these two mathematical terms are not same, and a big difference lies in their arrangement, that explains what they represent. The best way, to identify, whether a given problem is an expression or equation is to check, if it contains an equal to sign (=) or not. If it does, it is an equation, but if … [Read more...]

## Difference Between Sequence and Series

In mathematics and statistics, the line that demarcates sequence and series are thin and blurred, due to which many think that these terms are one and the same thing. Nevertheless, the notion of sequence differs from series in the sense that sequence refers to an arrangement in the particular order in which related terms follow each other. As opposed to series which denotes the summation of the elements of a sequence. Take a read of the article to know the significant difference between sequence … [Read more...]

## Difference Between Rational and Irrational Numbers

Mathematics is nothing but a number game. A number is an arithmetical value that can be a figure, word or symbol indicating a quantity, which has many implications like in counting, measurements, calculations, labelling, etc. Numbers can be natural numbers, whole numbers, integers, real numbers, complex numbers. Real numbers are further divided into rational numbers and irrational numbers. Rational numbers are the numbers which are integers and fractions while irrational numbers are the … [Read more...]

## Difference Between Discrete and Continuous Data

In statistics, data is defined as the facts and figures collected together for the purpose of analysis. It is divided into two broad categories, qualitative data, and quantitative data. Further, the qualitative data is sub-divided into nominal and ordinal data, while quantitative data is sub-classified as discrete and continuous data. Quantitative data is data that contains numerical values and uses range. Many think that the types of quantitative data are more or less same, but they are … [Read more...]

## Difference Between Mutually Exclusive and Independent Events

Probability is a mathematical concept, which has now become a full-fledged discipline and is a vital part of statistics. Random experiment in probability is a performance that generates a certain outcome, purely based on chance. The results of a random experiment are called event. In probability, there are various types of events, as in simple, compound, mutually exclusive, exhaustive, independent, dependent, equally likely, etc. Most of the students of statistics are confused between … [Read more...]

## Difference Between Binomial and Poisson Distribution

The theoretical probability distribution is defined as a function which assigns a probability to each possible outcomes of the statistical experiment. The probability distribution can be discrete or continuous, where, in the discrete random variable, the total probability is allocated to different mass points while in the continuous random variable the probability is distributed at various class intervals. Binomial distribution and Poisson distribution are two discrete probability distribution. … [Read more...]

## Difference Between Descriptive and Inferential Statistics

In today's fast-paced world, statistics is playing a major role in the field of research; that helps in the collection, analysis and presentation of data in a measurable form. It is quite hard to identify, whether the research relies on descriptive statistics or inferential statistics, as people usually, lacks knowledge about these two branches of statistics. As the name suggests, descriptive statistics is one which describes the population. On the other end, Inferential statistics is used to … [Read more...]

## Difference Between Rhombus and Parallelogram

In geometry, there are many types of a quadrilateral i.e. parallelogram, rhombus, square, rectangle, trapezium, and kite, which share common characteristics, due to which people face trouble in understanding these figures. Rhombus and Parallelogram are two such shapes that are frequently juxtaposed by the people, but there is a difference in their properties. While rhombus can be referred as a slanting square, whose adjacent sides are equal, the parallelogram is a slanting rectangle with two set … [Read more...]

## Difference Between Ratio and Proportion

Ratio and proportion are two mathematical concepts which have end number of practical applications in different spheres of life. The ratio is used to compare the quantities of two different categories like the ratio of men to women in the city. Here men and women are the two different categories. On the contrary, Proportion is used to find out the quantity of one category over the total, like the proportion of men out of total people living in the city. This article presents you the basic … [Read more...]

## Difference Between Correlation and Regression

Correlation and Regression are the two analysis based on multivariate distribution. A multivariate distribution is described as a distribution of multiple variables. Correlation is described as the analysis which lets us know the association or the absence of the relationship between two variables 'x' and 'y'. On the other end, Regression analysis, predicts the value of the dependent variable based on the known value of the independent variable, assuming that average mathematical relationship … [Read more...]
