Sampling Errors

Let's learn about Errors in Sampling in Statistics today.

When we sample data in statistics, many a times it is based on probability. In such cases the errors that arises are called sampling errors. In order to remove the different kinds of sampling errors below are the methods used:

• Increasing the sample size
• Stratification method

Next time i will help you to understand the concept of graphing data in statistics. Also one can get help from an expert tutor online. Not just in statistics but in other topics as well such as pre calculus tutoring and so on.

Fractions help

In today's post we will learn the concept of the relation between equivalent fraction and simplify fractions.

In order to decide whether two fractions are equivalent fraction, we need to simplify fractions. When two fractions are given, first the fractions needs to be simplified to smaller form and then compared.

As for example: Given fractions: 3/4 and 9/12
After simplifying: 3/4 and 3/4
Both are equal and therefore, 3/4 = 9/12.

For more help in this concept get connected to an online tutor and get your help. You can also avail to help for other subjects like biology tutoring and so on as well.

history of geometry

In this blog we will learn about history of geometry,

Geometry arose as the field of knowledge dealing with spatial relationships. Geometry was one of the two fields of pre-modern mathematics, the other being the study of numbers.History of geometry goes way back into the centuries.

Classic geometry was focused in compass and straightedge constructions. Geometry was revolutionized by Euclid, who introduced mathematical rigor and the axiomatic method still in use today. His book, The Elements is widely considered the most influential textbook of all time, and was known to all educated people in the West until the middle of the 20th century.Next we will learn about 4 grade math, The topics involved in four grade math are number sense, patterns, addition, measurement, subtraction, multiplication, functions, fractions & mixed numbers, division, algebra, decimals, adding and subtraction of decimals and probability & statistics. In this article we shall discuss about the example problems involved in four grade math.In the next blog we will learn about fraction simplifier.Hope you like the above example of history of geometry,please leave your comments if you have any doubts.

multiplying monomials

In this blog we will learn about multiplying monomials,again we can understand this with the help of an example.

Problem 1 for multiplying monomial:

(x³) (x⁴)

= x³⁺⁴

= x⁷

Problem 2 for multiplying monomial:

(x² y) ( x³ y ²)

= (x². x³) ( y . y²)

= x²⁺³ . y¹⁺²

= x⁵y³

Problem 3 for multiplying monomials:

( 6k⁵ ) ( 5k² )

= ( 30 k⁷) ( multiply numbers )

Problem 4 for multiplying monomial:

-4 ( m² n ) ( -3 m⁴ n³ )

= ( -4 . -3 ) ( m² . m⁴ ) ( n . n³ )

= ( 12 ) ( m²⁺⁴ ) ( n¹⁺³ )

= 12 m⁶ n^4.

^{Next we will learn about angle bisector theorem. An angle bisector is a portion tense from any peak of a polygon that cuts that weight into two rival angles. In all the trigon, the trey angles bisectors instrument meet at a singular quantity inside the triangle. If the bisector of the extremum standpoint of an Isosceles polygon is haggard, then the bisector is right to the part of the trilateral. Here we are accomplishment to see and confirm search bisector theorem.In the next blog we will learn about types of lines.Hope you like the above example of multiplying monomials,please leave your comments if you have any doubts.}

4th grade math problems

In this blog we will learn about 4th grade math problems,let us now look at few examples of 4th grade math problems, 4th grade math problems mainly cover addition, subtraction, multiplication, and division problems

1) Solve, 3(4+3) – 9 + 3(4)

Solution:
= 3(7) – 9 + 12
= 21 + 3
= 24

2) Solve, 5 + * 5 + 5

Solution:
= 5 + 2 * 5 + 5
= 5 + 10 + 5
= 20

3) Solve, 6² + 7²

Solution:

= (6 * 6) + (7 * 7)
= 36 + 49
= 85.

Next let us learn about four sided shapes,

Any four sided shape is called as quadrilateral . the following are the examples for four sided shapes, they are

1. Square

2. Rectangle.

3. Rhombus.

4. Parallelogram.In the next blog we will learn about percentage change calculator.Hope you like the above example of 4th grade math problems,please leave your comments if you have any doubts.
