Mean Formula For Unmarried Data

In everyday life, the average formula is to a greater extent than widely used, such every bit calculating the average value of students, nosotros must role the hateful formula to calculate the average value.

Mean Formula for Singel Date

Here is a formula for calculating avarage value :

x̄ = ∑x_i / n
x̄ = (x₁ + x₂ + x₃ + ... + x_n)/n

Information :

x̄ = Average Value
x_i= x₁ + x₂ + x₃ + ... + x_n
n = Amount of Data

Example :

Please elevate one's ask heed the average value of 6, 4, 8, 10, 11, 10, 7 !

Answer :

x_i= 6 + 4 + 8 + 10 + 11 + 10 + 7

n = 7

x̄ = ∑x_i / n
x̄ = (x₁ + x₂ + x₃ + ... + x_n)/n

x̄ = (6 + 4 + 8 + 10 + 11 + 10 + 7)/7

x̄ = 56 / 7

x̄ = 8

in addition to thence the average value of 6, 4, 8, 10, 11, 10, 7 is 8

2 Median Formulas For Unmarried Information Inwards Statistics

9:09 AM

The median is the middle value of a grouping of information that has been sorted yesteryear magnitude.

The median formula for unmarried information inwards statistics

at that spot are 2 formulas to decide the median of a data, The next is the median formula for a unmarried data:

1. The median formula if a lot of information is odd

Me = information place : (n + 1)/2

Information :

Me = Median Value

n = amount of data

Example :

Please decide the median of the information 3,7,6,4,5 !

Answer:

n = 5

The commence matter to create is form the data, then the information becomes 3,4,5,6,7

afterward that gear upward the median :

Me = information place : (n + 1)/2

Me = data location : (5 + 1)/2

Me = data location : 6/2

Me = data location : 3

So the median of information is inwards the tertiary place :

commence place = 3

minute place = 4

third place = 5

4th place = 6

5th place = 7

Me = Median place : three = tertiary place = 5

So the median of 3, 7, 6, 4, together with 5 is 5

2. The median formula if a lot of information is even

Me = ((data location : n/2) + (data location : ((n/2) + 1))2

Information :

Me = Median Value

n = amount of data

Example :

Please decide the median of 1, 2, 4, together with three !

Answer :

n = 4

first place = 1

second place = 2

third place = 3

fourth place = 4

The commence matter to create is form the data, then the information becomes 1, 2, 3, 4

afterward that gear upward the median :

Me = ((data location : n/2) + (data location : ((n/2) + 1))) / 2

Me = ((data location : 4/2) + (data location : ((4/2) + 1))) / 2

Me = ((data location : 2) + (data location : (2 + 1))) / 2

Me = ((data location : 2) + (data location : 3)) / 2

Me = (second location + tertiary location) / 2

Me = (2 + 3) / 2

Me = v / 2

Me = 2,5

So the median of 1, 2, 3, 4 is 2,5

So but this article which I tin laissez passer on the sack part to you.

Mode of a unmarried appointment inward statistic

The means of a information is information that oftentimes appears or information that has the highest frequency. To own upward one's heed the value of the means of a information is truly no formula. But to specify a unmarried information means tin sack last searched past times :

Mode Formulas of H5N1 Single Data In Statistic

Mo = the break or value that close appear

Information :

Mo = Mode

Example :

Please own upward one's heed the means value of 3,4,4,5,5,5,6,7 !

Answer :

The next is the break of information for each chemical ingredient :

3 = 1 frequency
4 = ii frequency

5 = iii frequency

6 = 1 frequency

7 = 1 frequency

The information alongside the close value is 5 alongside 3 frequency, then the means of 3,4,4,5,5,5,6,7 is 5.

Harmonic Mean Formulas

Average harmonic is the average calculated past times converting all information into fractions, of which the information value is used every bit the denominator in addition to the numerator is 1, hence all the fractions are summed in addition to hence used every bit the divisor of the amount of data.

Harmonic Mean Formulas inwards Statistic

H = n/(∑(1/x_i))

Information :

H = average harmonic value

n = amount of data

∑ = sigma notation

x_i = data

Example :

Please calculate the Harmonic hateful of 3,5,6,6,7,10,12!

Answer :

n = 7

x_i = 3,5,6,6,7,10,12

H = n/(∑(1/x_i))
H = 7/((1/3)+(1/5)+(1/6)+(1/6)+(1/7)+(1/10)+(1/12))
H = 7/((4/12)+(1/5)+(2/12)+(2/12)+(1/7)+(1/10)+(1/12))

H = 7/(((4+2+2+1)/12)+(1/5)+(1/7)+(1/10))

H = 7/((9/12)+(1/5)+(1/7)+(1/10))

H = 7/((9/12)+(2/10)+(1/7)+(1/10))

H = 7/((9/12)+((2+1)/10)+(1/7))

H = 7/((9/12)+(3/10)+(1/7))

H = 7/((9/12)+(21/70)+(10/70))

H = 7/((9/12)+((21+10)/70))

H = 7/((9/12)+(31/70))

H = 7/((630/840)+(372/840))

H = 7/((630+372)/840)

H = 7/((1002)/840)

H = seven x (840/1002)

H = 5880/1002

H = 5,87

So the harmonic average of 3,5,6,6,7,10,12 is 5,87

Geometric Hateful Inward Statistics

9:09 AM

Geometric Mean inwards Statistics is the average obtained past times multiplying all the information inwards a sample group, as well as thus it is rooted past times the total of the sample data.

Geometric Mean Formulas inwards Statistics

U = ⁿ√(x₁ . x₂ . x₃ . ... . x_n)

Information :

U = geometric hateful value
x = data

n = amount of data

Example :

Please cause upward one's hear geometric hateful of 2,4,8,16 !

Answer :

n = 4

x₁ = 2

x₂ = 4

x₃ = 8

x₄ = 16

U = ⁴√(x₁ . x₂ . x₃ . x₄)

U = ⁴√(2 . 4 . 8 . 16)

U = ⁴√(2¹ . 2² . 2³ . 2⁴)

U = ⁴√(2^1+2+3+4)

U = ⁴√2¹⁰

U = 2^10/4

U = 2^5/2

U = √2⁵

U = √32

U = √(16 x 2)

U = √16 x √2

U = 4√2

So the geometric mean of 2,4,8,16 is 4√2

Quartile Formulas Of Unmarried Information Inward Statistics

Quartile Formulas of Single Data inwards Statistics

Quartile carve upwards the information into 4 equal parts from information which has been sorted 25% each.

Quartile Formulas of Single Data inwards Statistics

Q_i = location of information : (i(n + 1))/4

Information :

Q_i = value of kuratil - ith

n = total of data

Example :

Please own upwards one's heed the 1st quartile value of 1, 6, 9, 3, 5, 8, 10 !!!

Answer :

kind the information from the smallest information to the largest information :

1st place = 1

2nd place = 3

3rd place = 5

4th place = 6

5th place = 8

6th place = 9

7th place = 10

n = 7

hence the quartile is :

Q_i = location of information : (i(n + 1))/4

Q₁ = location of information : (1(7 + 1))/4

Q₁ = location of information : (1(8))/4

Q₁ = location of information : 8/4

Q₁ = location of information : 2

Q₁ = location of information : 2nd

Q₁ = 2d location

Q₁ = 3
