Level of Measurement

Let's learn about the level of measurement in statistics in today's post.

There are four levels of measurement used in applied statistics. These four levels of measurement are as follows:

• Ordinals
• Intervals
• Nominal
• Ratio scales

Next time i will help you with the concept of statistical formula. Till then enjoy this learning and for more help you can connect with an online tutor and get your help. Not just statistics help but one can avail to algebra, geometry tutoring as well.

Comparing Fractions

Comparing Fractions is one of the important concepts of fractions. In today's session, we will confine our learning to comparing fractions.

Comparing fractions is nothing but comparing two fractions in terms which one is greater, smaller and equal. In case of bigger fractions, the fractions are simplified in the first step. After simplify fractions is done, both the fractions are compared. As for example 2/3 and 7/8 are two given fractions. After comparing the fractions, we come to know that 7/8 is greater than 2/4.

For more help with this topic, understand the concept from an online tutor. Not just fractions, one can avail to calculus tutoring and so on.

Next time, we will move on to some other topic, till then keep practicing these problems. Also do post your feed backs.

PRIME NUMBERS

Prime Numbers are studied under Arithmetic under Math. The Number system is classified into different types based on their properties as:

• Whole Numbers
• Natural Numbers
• Rational and Irrational numbers
• Integers
• Prime Numbers

Prime Numbers are a type of numbers discussed here. Prime Numbers are those numbers which are divisible only by themselves and 1. For example :13 is only divisible by itself and 1.
In other words, prime Numbers are those which do not have any other factors apart from themselves and 1.

Prime numbers have the following characteristics:

• 2 is the only Prime number
• 0 and 1 cannot be considered as Prime numbers
• A number ending with 5 or 0 is never prime as it is divisible by 5.

Students have to learn to differentiate between the kinds of numbers. The prime numbers are often used in finding Prime factors of a number(Prime factorization). Students should also learn about divisibility and the rules of divisibility.

Solve for x

How to solve for x

Example 1: solve 3x 10 = 2x 5

Solution:

Step 1: First write the equation, in this equation we have to find the variable of x

3x + 10 = 2x + 5

Step 2: subtract 10 on both side, we take only left hand side

3x + 10 – 10 = 2x + 5 - 10

3x = 2x - 5

Step 4: subtract 2x on both side

3x – 2x = 2x – 5 - 2x

x = -5

Triangle Square

Triangle square:

Find the area and perimeter of triangle whose side 12 cm.

Sol:

All sides of equilateral triangle area equal.

Side of triangle, a = 12 cm

Area of the triangle (A) = a² x

= 12² x (1.732/4)

= 144 x 0.433

= 62.352 cm²

Perimeter of equilateral triangle (P) = 3a

= 3 x 12

= 36cm

Quadrants

Quadrants of a graph:

Division is the chat helps us describes the parts. If you draw beeline and erect lines, bisect the page into four parts, anniversary alleged a division graph.

Blueprint contains four quadrants.

Large bulk acclimated one is the 1st quadrants blueprint which is on the top right.

The larboard of it is declaring the additional quadrants.

The third is the one beneath the additional quadrants.

One on the blueprint that is beneath the aboriginal division is defined the fourth quadrants graphs.

A rectangle allowance the abject of the allowance is 28m and acme of the allowance 22m. The amount of bark the allowance is $18 per aboveboard meter; acquisition the absolute amount for white abrasion the absolute room.

Solution:

Let abject of the allowance b = 28 and

Height of the allowance h = 22.

The blueprint for breadth of the rectangle = abject Г— acme Therefore 28 Г— 22

= 616 sq. meters.

The amount of bark 1sq. beat is [$] 18,

The amount for bark the absolute allowance = 18 Г—616 = [$] 11088.

Bar Graph

A bar blueprint is a graphical analogy of abundance distributions of ungrouped information. It is a aesthetic affirmation of the arithmetical abstracts by a amount of confined of compatible amplitude erected angular with like agreement amid them.

Construction of Bar Graphs

The accomplish to draw a bar graphs are

Step 1:Draw accumbent and vertical axes on the blueprint paper.

Step 2:Take one set of the abstracts forth x-axis and added set of abstracts in y-axis.

Step 3:Now artifice the confined application accustomed data.

A line plot

A line pot

In order to plot a line plot a horizontal line is drawn with an appropriate scale with units matching the given information. For an occurrence of a number in the information an x is marked above the corresponding number on the plotted line. If the number is repeated another x is marked above the earlier x. This step is completed for the whole information. The resulting figure is called as a line plot.

Linear Programming

Linear Programming Examples:

Step1. Identify the unknowns in the given LPP. Denote then by x & y.
Step2. Formulate the aim function in terms of x & y. be sure whether it is to be maximized or
minimized.

Step3. Translate all the constraints in the kind of linear inequations.
Step4. Solve these in equations simultaneously. Mark the common area by shaded region. This is the

feasible region .
Step5. Find the coordinates of all the vertices of the feasible region
Step6. Find the worth of the aim function at each vertex of the feasible region.
Step7. Find the values of x & y for which the aim function

z = ax + by has maximum or maximum value
