Analyze Statistical Data

Statistics is a study of data collection and therefore the concept of analyzing statistical data is very important. Any collection of information is called data. In order to measure the statistical data and analyze it the measures of central tendency are used: mean, median, mode and range. Also mean is the most importantly used in analyze statistical data.

statistics linear regression

Linear Regression Definition states that it can be measured by using lines of regression. Regression measures the amount of average relationship or mathematical relationship between variables in terms of original units of knowledge. Whereas, correlation measures the nature of relationship between variables. i.e.., positive or negative or uncorrelated.

Triangle Calculator

Triangle calculator

Triangle is one of the basal shapes in geometry. The absolute auto genous bend of triangle is consistently according to 180 degree. Absolute apparent breadth is the breadth which is affected for the three dimensional shapes. Absolute apparent cannot be affected for two dimensional shapes. Absolute apparent breadth can be affected for cone, cube, cylinder, prism, pyramid and sphere. In this commodity we are traveling to see about triangle apparent breadth calculator.

Trignomerty Problems

-->Trignometry Examples

Question: Evaluate f(x) at x = -3, by synthetic division.
f(x ) = x³ - 3x² + 2x + 2.

A ) -8
B ) -58
C ) -43
D ) -52

Steps to derive

1 f(x) = x³ - 3x² + 2x + 2

2 Use the synthetic division.

3 -3| 1 -3 2 2
-3 18 -60
----------------------------
1 -6 20 -58
----------------------------

4 f(-3) = -58
Hence the right answer is Option B

Probability

Probability problems
We studied about the idea of normal probability as a measure of uncertainty of various phenomenons. They have obtained the probability of getting an even number in throwing a die as 3 / 6 = 1 / 2. Here the total feasible outcomes are 1, 2, 3, 4, 5 and 6 (five in number). event of ‘getting an even number’ are 2, 4, 6 (i.e., four in number).

In general, to get the normal probability of an event, they find the ratio of the number of outcomes favorable to the event, to the total number of equally likely outcomes.
let us do some issues on normal probability.

Introduction to infinite limits

Introduction to Infinite Limits Help:
The function has variable. By applying limit for the variable in function, we get the result of the function. As like as, by applying limit with the help of infinite to the variable of the function, we get the result. Thus by the help of limit given the variable as infinity in the function gives the result. For example: this article we see about how to solve the function with help of limit as infinite.
