Skewness, in basic terms, implies off-centre, so does in statistics, it means lack of symmetry. With the help of skewness, one can identify the shape of the distribution of data. Kurtosis, on the other hand, refers to the pointedness of a peak in the distribution curve. The main difference between skewness and kurtosis is that the former talks of the degree of symmetry, whereas the latter talks of the degree of peakedness, in the frequency distribution. Data can be distributed in many ways, … [Read more...]

The state can be understood as the constituent division, which possesses a separate government. Conversely, Union Territory is a small administrative unit, that is ruled by the Union. India, a country located in the South Asia, is among the largest country in the world. It is a federal country, i.e. here the power is distributed among the central and various units. When it comes to administrative divisions of the country, after the inclusion of Telangana there are total 29 states and 7 Union … [Read more...]

In mathematics, you might have noticed superscript, i.e. a little digit that is placed above and to the right of any number. The large the number is the difficult is to read, compare and operate and due to this reason, superscripts are used to convert larger numbers into the smallest form. This is done with the help of powers and exponents, that are the basic concept of mathematics but are also juxtaposed by many students. Exponents represent the number of times the base is multiplied. On the … [Read more...]

Latitude alludes to the horizontal lines that represent the distance of any point, north or south of the equator, its direction is east to west. On the other hand, longitude implies the vertical lines indicating the distance of any point, east or west of the prime meridian, its direction is north to south. Latitudes are also known as parallels while longitudes are termed as meridians. On earth's surface, locations are determined by the two reference lines known as latitude and longitude. In … [Read more...]

As we know that the shape of the earth is not perfectly spherical because it is a bit flattened at both the north and south poles and bulge in the centre. Every person is curious to know, how our earth looks like in the universe, but there are only handful of persons who can travel space and see it live. One can have an idea of earth's appearance, with a globe. A globe is a miniature form of the earth, which represents distances, directions, continents, oceans, countries, etc. A globe is … [Read more...]

Mathematics is a game of numbers, where we study number, its types and the concepts relating to it. Arithmetic is that branch of mathematics which focuses on properties and manipulation of numbers. Factors and multiples are two key concepts studied together in arithmetic, at the elementary level. A factor is a number that leaves no remainder behind after it divides the specific number. On the contrary, multiple is a number reached by multiplying a given number by another. While factors of a … [Read more...]

Port can be understood as a place, where loading and unloading of ships and boats are done. The term port is often juxtaposed with harbour, which implies a place along a coast where ships or boats can take shelter if the atmospheric conditions are not well for sailing. While ports are man-made, harbours can be natural or man-made. Many times they serve similar purposes relating to administration, development, industry and commerce. And due to this reason, there is always a buzz, whenever … [Read more...]

There are primarily two types of errors that occur, while hypothesis testing is performed, i.e. either the researcher rejects H0, when H0 is true, or he/she accepts H0 when in reality H0 is false. So, the former represents type I error and the latter is an indicator of type II error. The testing of hypothesis is a common procedure; that researcher use to prove the validity, that determines whether a specific hypothesis is correct or not. The result of testing is a cornerstone for accepting or … [Read more...]

The two ways of carrying out statistical significance test of a characteristic, drawn from the population, with respect to the test statistic, are a one-tailed test and two-tailed test. The one-tailed test refers to a test of null hypothesis, in which the alternative hypothesis is articulated directionally. Here, the critical region lies only on one tail. However, if the alternative hypothesis is not exhibited directionally, then it is known as the two-tailed test of the null hypothesis., … [Read more...]

ANOVA is an effective technique for carrying out researches in various disciplines like business, economics, psychology, biology and education when there are one or more samples involved. It is often misconstrued with ANCOVA, as both are used to check the variance in the mean values of the dependent variable associated as a result of controlled independent variables, after considering the consequences of the uncontrolled independent variable. ANOVA is used to compare and contrast the means of … [Read more...]
