The two phenomena based on straight light propagation are reflection and refraction, wherein the reflection deals with the bouncing of light rays whereas the refraction talks about bending of light rays. Our world is full of objects that we can see only with the help of light. If there is the absence of light in a room, nothing is visible to us. Have you ever wondered, how can we perceive things with eyes? In the daytime, it is the light rays coming from the sun, that help us to see objects, … [Read more...]
Difference Between Stars and Planets
At night, when you look up high in the sky, you will notice trillions of shining dots, out of which some appear brighter, some are bigger while some of them twinkle. It is a point to ponder, what are these bright dots? So they are nothing but stars and planets. Stars are heavenly bodies that possess their own light and twinkle. They are fixed and large luminous body like the Sun. On the flip side, planets are celestial objects, which have an apparent motion of their own and also moves around … [Read more...]
Difference Between Reuse and Recycle
The way, we handle wastes has a great impact on the global environment, i.e. our ecosystem. In our school life, all of us have been taught an eco-friendly 'mantra', with the help of which wastes can be managed or disposed off effectively, with least harm to the environment. The rule is, Reduce, Reuse and Recycle, often known as 3R's. While reuse implies using the same item or natural resource, again and again, recycle alludes to the transformation of waste item to a useful one. Most of the … [Read more...]
Difference Between Type I and Type II Errors
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...]
Difference Between One-tailed and Two-tailed Test
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...]
Difference Between ANOVA and ANCOVA
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.

ANOVA is used to compare and contrast the means of … [Read more...]
Difference Between T-test and F-test
Hypothesis testing starts with setting up the premises, which is followed by selecting a significance level. Next, we have to choose the test statistic, i.e. t-test or f-test. While t-test is used to compare two related samples, f-test is used to test the equality of two populations. The hypothesis is a simple proposition that can be proved or disproved through various scientific techniques and establishes the relationship between independent and some dependent variable. It is capable of … [Read more...]
