To make the generalisation about the population from the sample, statistical tests are used. A statistical test is a formal technique that relies on the probability distribution, for reaching the conclusion concerning the reasonableness of the hypothesis. These hypothetical testing related to differences are classified as parametric and nonparametric tests.The parametric test is one which has information about the population parameter. On the other hand, the nonparametric test is one where … [Read more...]

## Difference Between Histogram and Bar Graph

The fundamental difference between histogram and bar graph will help you to identify the two easily is that there are gaps between bars in a bar graph but in the histogram, the bars are adjacent to each other. After the collection and verification of data, it needs to be compiled and displayed in such a way that it highlights the essential features clearly to the users. The statistical analysis can only be performed if it is properly presented. There are three modes of presentation of data … [Read more...]

## Difference Between Area and Perimeter

Area and perimeter are two vital fundamental concepts of mathematics, which are often understood together. These two concepts are used to measure the physical space of an object and forms a foundation for advanced mathematics. The perimeter is often understood as the length of the path that covers a closed figure while the area refers to the space covered by the closed figure. Both the concepts have practical application and are used in our day to day life. While the area is nothing but the … [Read more...]

## Difference Between Mean and Median

Central tendency implies the tendency of the data points to cluster around its central or middle-most value. The two most commonly used measures of central tendency are mean and median. Mean is defined as the 'central' value of the given set of data whereas median is the 'middle-most' value in the given set of data. An ideal measure of central tendency is one which is clearly defined, easily understood, simply calculable. It should be based on all observations and least affected by extreme … [Read more...]

## Difference Between Variance and Standard Deviation

Dispersion indicates the extent to which observations deviate from an appropriate measure of central tendency. Measures of dispersion fall into two categories i.e. an absolute measure of dispersion and relative measure of dispersion. Variance and standard deviation are two types of an absolute measure of variability; that describes how the observations are spread out around the mean. Variance is nothing but the average of the squares of the deviations, Unlike, standard deviation is the square … [Read more...]

## Difference Between Permutation and Combination

In mathematics, you might have heard the notions of permutation and combination end number of times, but have you ever imagined that these two are different concepts? The fundamental difference between permutation and combination is the order of objects, in permutation the order of objects is very important, i.e. the arrangement must be in the stipulated order of the number of objects, taken only some or all at a time. As against this, in the case of a combination, the order does not matter … [Read more...]

## Difference Between Formative and Summative Assessment

Assessment refers to the evaluation of something. When it comes to learning, students are assessed by the educational institution, to analyse their learning graph, their understanding level and progress. It also helps in planning further study material. Assessment can be of two types, i.e. it can be formative or summative. The formative assessment (FA) is conducted during the learning process. On the contrary, summative assessment (SA) is undertaken only at the end of the course or unit. The … [Read more...]

## Difference Between Training and Education

In general sense, the term training implies the act of imparting a special skill or behavior to a person, which is commonly offered to employees of operational level. It is not exactly same as education, which is a process of systematic learning something in an institution that develops a sense of judgment and reasoning in employees. It is offered to all employees equally, irrespective of their grades or level in the corporate ladder. These two are so closely intertwined that with the passage … [Read more...]

## Difference Between Apprenticeship and Internship

In on-the-job training, the training is provided to the trainees, at the actual work location. There are several on-the-job training methods like orientation, coaching, job instruction, apprenticeship, and internship. Out of these methods, internship and apprenticeship are frequently misconstrued, but they are different. In apprenticeship, the trainee undergoes a training in which all the skills required for a particular occupation or trade are being taught. In this, the trainee gets hands-on … [Read more...]

## Difference Between GRE and GMAT

At present, students are very much concerned as well as aware of their education and career. They want to pursue the best course from the top school or college. GRE and GMAT are considered as the pathway for studying abroad in the leading universities, which are conducted by two different bodies. Qualifying Graduate Record Examination (GRE) makes you eligible for taking admission in the graduate schools. On the other hand, the Graduate Management Admission Test (GMAT) is the entry door for … [Read more...]
