bar graph examples

Let us learn about bar graphs & bar graph examples

Bar graphs are probably the most famous & most widely used graph types. Bar graphs allow a graphical representation of data in different groups & categories. The length of a bar characterize the numerical amount for a given series point.
Bar graphs are a very general type of graph best suited for a qualitative independent variable. Hence there is no uniform distance between the discrete nature of the individual bars & levels of a qualitative variable are well suited for this type of independent variable. Though you can extract trends between bars e.g., they are gradually getting longer or shorter, we cannot calculate a slope from the heights of the bars.
a) Simple bar graph (b) Double bar graph & (c) Divided bar graph are 3 types of bar graph

mean deviation calculator

Let us learn about mean deviation calculator

The difference between observed value & the expected value of a function is said to be as mean of deviation. The mean deviation is nothing but the mean of the absolute deviation of a set of data about the data's mean. mean deviation is an important expressive statistic which is not frequently used in mathematical statistics. This is essentially mean deviation as the "mean deviation from the mean," the introduction of the complete value makes logical calculations using this statistic much more difficult.

Find the mean deviation for the given values.

16, 22, 10, 32

Sol: Mean (avg) = 20

Deviation(Variation) = -4, 2, -10, and 12

absolute deviation = 4, 2, 10, and 12

Sum of the absolute deviation = 28

mean deviation = 7

Find the mean for the given values.

24, 11, 40

Sol: Mean (avg) = 25

Deviation = -1, -14, and 15

absolute deviation = 1, 14, and 15

Sum of the absolute deviation = 30

mean deviation = 10

composite numbers 1-100

Let Us learn about composite numbers 1-100


Numbers that have more than 2 factors are said to be as composite number. The smallest composite number is four.
The Examples of composite number are as follows:
4, 6, 8, 10, 12, etc.
Note: That numerical ' 1 ' is neither composite number nor prime number, because it has only 1 factor which is 1 itself.

Any composite number will be written as the product of 2 or more prime numbers & this combination is unique for every number. That is the reason, all the natural numbers can be obtained by adding prime numbers in different combination.

advantage and disadvantage of computer

Let learn how computer is useful in learning math.

Advantage and disadvantage of computer

Faster Communication, Massive increase in productivity, Multiple functions in work and entertainment, Keeps kids quite and destroying the house, Massive Storehouse of information Children learns to read and write through computer games instead of homemade flash cards, books, and tutorials & during their learning time computers come in more demands. Projects, reports research, Assignments, are accessed through internet rather than spending money for expensive books. Even their bedtime stories are easily accessed through the internet.

Advantage and disadvantage of computer

Addiction, Minor increase in cancer due to radiation (though unproven),Uses a lot of electricity, Increases Child maturity at ages far below average, Risk of credit card and ID theft.

factoring calculator

Let us learn about factoring calculator

factoring calculator may be a manual or online calculator, which is used to find the factors of a given polynomial. The factoring calculator may be programmed based on quadratic formula for factoring quadratic equations, or factoring by grouping and completing the squares for factoring polynomials like quadratic polynomials & quadratic cubic

Factor the given expression, 2x² + 4x
Solution:
= 2x² + 4x
Taking the common terms outside,
= 2x(x + 2)
The answer is 2x (x+2).
