Variance vs Standard Deviation Variation is the common phenomenon in the study of statistics because had there been no variation in a data, we probably would not need statistics in the first place. Variation is described as variance in statistics which is a measure of the distance of the values from their mean. Variance is […]
Difference Between Classification and Regression
The key difference between classification and regression tree is that in classification the dependent variables are categorical and unordered while in regression the dependent variables are continuous or ordered whole values. Classification and regression are learning techniques to create models of prediction from gathered data. Both techniques are graphically presented as classification and regression trees, […]
Difference Between Multistage Sampling and Sequential Sampling
Multistage Sampling vs Sequential Sampling Sampling is one of the most important aspects in every walk of life. Sampling is required by every one from institutions to Governments and from a small community to big industry. Sampling provides the results that are used to make decisions that have significance bearing on the future. Sampling is […]
Difference Between Circle and Sphere
Circle vs Sphere Circle and sphere are both round in shape but whereas a circle is a figure, a sphere is an object. You can compare the two as a drawing of a tennis ball on a piece of paper and the ball itself in real life. A circle is a 2D figure whereas a […]
Difference Between Bezier Curve and B-Spline Curve
Bezier Curve vs B-Spline Curve In numerical analysis in mathematics and in drawing computer graphics, many types of curves are taken help of. Bezier Curve and B-Spline Curve are two of the popular models for such analysis. There are many similarities in these two types of curves and experts call B-Spline curve to be a […]
Difference Between Fourier Series and Fourier Transform
Fourier Series vs Fourier Transform Fourier series decomposes a periodic function into a sum of sines and cosines with different frequencies and amplitudes. Fourier series is a branch of Fourier analysis and it was introduced by Joseph Fourier. Fourier Transform is a mathematical operation that breaks a signal in to its constituent frequencies. The original […]
Difference Between DDA and Bresenham Algorithm
DDA vs Bresenham Algorithm DDA and Bresenham Algorithm are terms you would have come across when studying computer graphics. Before explaining the difference between these two term, let’s see what is DDA and what is Bresenham Algorithm. The invention of computer made things simple and one of them being solving of differential equations. Earlier it was done by […]
Difference Between Coefficient and Constant
Coefficient vs Constant When two things co-vary, there are two possibilities. One is that the change in a thing is concomitant with the change in another. When the age of a kid increases, there is a simultaneous increase in his height. The older the child the taller he is. The second possibility is that two […]
Difference Between Z Score and T Score
Z Score vs T Score Z score and T score are used in statistics and are referred to as standard scores. They indicate how many SD an observation in a data is above or below the mean. Most commonly used in a z-test, z-score is similar to T score for a population. It is similarities […]
Difference Between Probability and Chance
Probability vs Chance The two terms probability and chance are closely related and thus many get confused with these words. Chance is a word that is commonly used in everyday life situation, mostly in games of luck where chances of a particular event taking place are discussed. A student may have very good or bright chance […]
