Ranked Data Calculation

Sort our number set in ascending order

and assign a ranking to each number:

Ranked Data Table

Step 2: Using original number set, assign the rank value:

Since we have 5 numbers in our original number set,
we assign ranks from lowest to highest (1 to 5)

Our original number set in unsorted order was 5,35,81,83,92

Our respective ranked data set is 1,2,3,4,5

Root Mean Square Calculation

where A = x₁² + x₂² + x₃² + x₄² + x₅² and N = 5 number set items

Calculate A

A = 5² + 35² + 81² + 83² + 92²

A = 25 + 1225 + 6561 + 6889 + 8464

A = 23164

Calculate Root Mean Square (RMS):

RMS = 68.064675125942

Central Tendency Calculation

Central tendency contains:
Mean, median, mode, harmonic mean,
geometric mean, mid-range, weighted-average:

Calculate Mean (Average) denoted as μ

μ = 59.2

Calculate the Median (Middle Value)

Since our number set contains 5 elements which is an odd number,
our median number is determined as follows:

Number Set = (n₁,n₂,n₃,n₄,n₅)

Median Number = Entry ½(n + 1)

Median Number = Entry ½(6)

Median Number = n₃

Therefore, we sort our number set in ascending order

Our median is entry 3 of our number set highlighted in red:

(5,35,81,83,92)

Median = 81

Calculate the Mode - Highest Frequency Number

The highest frequency of occurence in our number set is 1 times
by the following numbers in green:

()

Since the maximum frequency of any number is 1, no mode exists.

Mode = N/A

Calculate Harmonic Mean:

With N = 5 and each x_i a member of the number set you entered, we have:

Harmonic Mean = 18.951248119369

Calculate Geometric Mean:

Geometric Mean = (x₁ * x₂ * x₃ * x₄ * x₅)^1/N

Geometric Mean = (5 * 35 * 81 * 83 * 92)^1/5

Geometric Mean = 108240300^0.2

Geometric Mean = 40.446206743856

Calculate Mid-Range:

Mid-Range = 48.5

Stem and Leaf Plot

Take the first digit of each value in our number set

Use this as our stem value

Use the remaining digits for our leaf portion

Sort our number set in descending order:

Basic Stats Calculations

Mean, Variance, Standard Deviation, Median, Mode

Calculate Mean (Average) denoted as μ

μ = 59.2

Calculate Variance denoted as σ²

Let's evaluate the square difference from the mean of each term (X_i - μ)²:

(X₁ - μ)² = (5 - 59.2)² = -54.2² = 2937.64

(X₂ - μ)² = (35 - 59.2)² = -24.2² = 585.64

(X₃ - μ)² = (81 - 59.2)² = 21.8² = 475.24

(X₄ - μ)² = (83 - 59.2)² = 23.8² = 566.44

(X₅ - μ)² = (92 - 59.2)² = 32.8² = 1075.84

Adding our 5 sum of squared differences up

ΣE(X_i - μ)² = 2937.64 + 585.64 + 475.24 + 566.44 + 1075.84

ΣE(X_i - μ)² = 5640.8

Use the sum of squared differences to calculate variance

Calculate the Standard Error of the Mean:

Calculate Skewness:

Let's evaluate the square difference from the mean of each term (X_i - μ)³:

(X₁ - μ)³ = (5 - 59.2)³ = -54.2³ = -159220.088

(X₂ - μ)³ = (35 - 59.2)³ = -24.2³ = -14172.488

(X₃ - μ)³ = (81 - 59.2)³ = 21.8³ = 10360.232

(X₄ - μ)³ = (83 - 59.2)³ = 23.8³ = 13481.272

(X₅ - μ)³ = (92 - 59.2)³ = 32.8³ = 35287.552

Add our 5 sum of cubed differences up

ΣE(X_i - μ)³ = -159220.088 + -14172.488 + 10360.232 + 13481.272 + 35287.552

ΣE(X_i - μ)³ = -114263.52

Calculate skewnes

Skewness = -0.75386103241978

Calculate Average Deviation (Mean Absolute Deviation) denoted below:

Evaluate the absolute value of the difference from the mean

|X_i - μ|:

|X₁ - μ| = |5 - 59.2| = |-54.2| = 54.2

|X₂ - μ| = |35 - 59.2| = |-24.2| = 24.2

|X₃ - μ| = |81 - 59.2| = |21.8| = 21.8

|X₄ - μ| = |83 - 59.2| = |23.8| = 23.8

|X₅ - μ| = |92 - 59.2| = |32.8| = 32.8

Average deviation numerator:

Σ|X_i - μ| = 54.2 + 24.2 + 21.8 + 23.8 + 32.8

Σ|X_i - μ| = 156.8

Calculate average deviation (mean absolute deviation)

Average Deviation = 31.36

Calculate the Median (Middle Value)

Since our number set contains 5 elements which is an odd number,
our median number is determined as follows:

Number Set = (n₁,n₂,n₃,n₄,n₅)

Median Number = Entry ½(n + 1)

Median Number = Entry ½(6)

Median Number = n₃

Therefore, we sort our number set in ascending order

Our median is entry 3 of our number set highlighted in red:

(5,35,81,83,92)

Median = 81

Calculate the Mode - Highest Frequency Number

The highest frequency of occurence in our number set is 1 times
by the following numbers in green:

()

Since the maximum frequency of any number is 1, no mode exists.

Mode = N/A

Calculate the Range

Range = Largest Number in the Number Set - Smallest Number in the Number Set

Range = 92 - 5

Range = 87

Calculate Pearsons Skewness Coefficient 1:

Since no mode exists, we do not have a Pearsons Skewness Coefficient 1

Calculate Pearsons Skewness Coefficient 2:

PSC2 = -1.9471

Calculate Entropy:

Entropy = Ln(n)

Entropy = Ln(5)

Entropy = 1.6094379124341

Calculate Mid-Range:

Mid-Range = 48.5

Calculate the Quartile Items

We need to sort our number set from lowest to highest shown below:

{5,35,81,83,92}

Calculate Upper Quartile (UQ) when y = 75%:

V = 4 ← Rounded down to the nearest integer

Upper quartile (UQ) point = Point # 4 in the dataset which is 83

Calculate Lower Quartile (LQ) when y = 25%:

V = 2 ← Rounded up to the nearest integer

Lower quartile (LQ) point = Point # 2 in the dataset which is 35

5,35,81,83,92

Calculate Inter-Quartile Range (IQR):

IQR = UQ - LQ

IQR = 83 - 35

IQR = 48

Calculate Lower Inner Fence (LIF):

Lower Inner Fence (LIF) = LQ - 1.5 x IQR

Lower Inner Fence (LIF) = 35 - 1.5 x 48

Lower Inner Fence (LIF) = 35 - 72

Lower Inner Fence (LIF) = -37

Calculate Upper Inner Fence (UIF):

Upper Inner Fence (UIF) = UQ + 1.5 x IQR

Upper Inner Fence (UIF) = 83 + 1.5 x 48

Upper Inner Fence (UIF) = 83 + 72

Upper Inner Fence (UIF) = 155

Calculate Lower Outer Fence (LOF):

Lower Outer Fence (LOF) = LQ - 3 x IQR

Lower Outer Fence (LOF) = 35 - 3 x 48

Lower Outer Fence (LOF) = 35 - 144

Lower Outer Fence (LOF) = -109

Calculate Upper Outer Fence (UOF):

Upper Outer Fence (UOF) = UQ + 3 x IQR

Upper Outer Fence (UOF) = 83 + 3 x 48

Upper Outer Fence (UOF) = 83 + 144

Upper Outer Fence (UOF) = 227

Calculate Suspect Outliers:

Suspect Outliers are values between the inner and outer fences

We wish to mark all values in our dataset (v) in red below such that -109 < v < -37 and 155 < v < 227

5,35,81,83,92

Calculate Highly Suspect Outliers:

Highly Suspect Outliers are values outside the outer fences

We wish to mark all values in our dataset (v) in red below such that v < -109 or v > 227

5,35,81,83,92

Calculate weighted average

Weighted-Average Formula:

Multiply each value by each probability amount

We do this by multiplying each X_i x p_i to get a weighted score Y

Weighted Average = NAN

Frequency Distribution Table

Show the freqency distribution table for this number set

5, 35, 81, 83, 92

Determine the Number of Intervals using Sturges Rule:

We need to choose the smallest integer k such that 2^k ≥ n where n = 0

Therefore, we use 0 intervals

Our maximum value in our number set of 92 - 5 = 87

Each interval size is the difference of the maximum and minimum value divided by the number of intervals

Add 1 to this giving us INF + 1 = INF
