Calculate the Median (Middle Value)

Since our number set contains 14 elements which is an even number,
our median number is determined as follows

Number Set = (n1,n2,n3,n4,n5,n6,n7,n8,n9,n10,n11,n12,n13,n14)

Median Number 1 = ½(n)

Median Number 1 = ½(14)

Median Number 1 = Number Set Entry 7

Median Number 2 = Median Number 1 + 1

Median Number 2 = Number Set Entry 7 + 1

Median Number 2 = Number Set Entry 8

For an even number set, we average the 2 median number entries:

Median = ½(n7 + n8)

Therefore, we sort our number set in ascending order

Our median is the average of entry 7 and entry 8 of our number set highlighted in red:

(13.29,14.70,16.58,16.58,25.51,27.86,33.03,34.44,39.14,39.61,42.43,44.31,47.13,57.47)

Calculate the Median (Middle Value)

Since our number set contains 14 elements which is an even number,
our median number is determined as follows

Number Set = (n1,n2,n3,n4,n5,n6,n7,n8,n9,n10,n11,n12,n13,n14)

Median Number 1 = ½(n)

Median Number 1 = ½(14)

Median Number 1 = Number Set Entry 7

Median Number 2 = Median Number 1 + 1

Median Number 2 = Number Set Entry 7 + 1

Median Number 2 = Number Set Entry 8

For an even number set, we average the 2 median number entries:

Median = ½(n7 + n8)

Therefore, we sort our number set in ascending order

Our median is the average of entry 7 and entry 8 of our number set highlighted in red:

Calculate the Quartile Items

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

{13.29,14.70,16.58,16.58,25.51,27.86,33.03,34.44,39.14,39.61,42.43,44.31,47.13,57.47}

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

V  =  y(n + 1)
  100

V  =  75(14 + 1)
  100

V  =  75(15)
  100

V  =  1125
  100

V = 11 ← Rounded down to the nearest integer

Upper quartile (UQ) point = Point # 11 in the dataset which is 42.43

13.29,14.70,16.58,16.58,25.51,27.86,33.03,34.44,39.14,39.61,42.43,44.31,47.13,57.47

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

V  =  y(n + 1)
  100

V  =  25(14 + 1)
  100

V  =  25(15)
  100

V  =  375
  100

V = 4 ← Rounded up to the nearest integer

Lower quartile (LQ) point = Point # 4 in the dataset which is 16.58

13.29,14.70,16.58,16.58,25.51,27.86,33.03,34.44,39.14,39.61,42.43,44.31,47.13,57.47

Calculate Inter-Quartile Range (IQR):

IQR = UQ - LQ

IQR = 42.43 - 16.58

IQR = 25.85

Calculate Lower Inner Fence (LIF):

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

Lower Inner Fence (LIF) = 16.58 - 1.5 x 25.85

Lower Inner Fence (LIF) = 16.58 - 38.775

Lower Inner Fence (LIF) = -22.195

Calculate Upper Inner Fence (UIF):

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

Upper Inner Fence (UIF) = 42.43 + 1.5 x 25.85

Upper Inner Fence (UIF) = 42.43 + 38.775

Upper Inner Fence (UIF) = 81.205

Calculate Lower Outer Fence (LOF):

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

Lower Outer Fence (LOF) = 16.58 - 3 x 25.85

Lower Outer Fence (LOF) = 16.58 - 77.55

Lower Outer Fence (LOF) = -60.97

Calculate Upper Outer Fence (UOF):

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

Upper Outer Fence (UOF) = 42.43 + 3 x 25.85

Determine the Number of Intervals using Sturges Rule:

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

Therefore, we use 0 intervals

Our maximum value in our number set of 57.47 - 13.29 = 44.18

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

Interval Size  =  44.18
  0

Add 1 to this giving us INF + 1 = INF

What 20 concepts are covered in the Basic Statistics Calculator?

average deviation
Mean of the absolute values of the distance from the mean for each number in a number set
basic statistics
central tendency
a central or typical value for a probability distribution. Typical measures are the mode, median, mean
entropy
refers to disorder or uncertainty
expected value
predicted value of a variable or event
E(X) = ΣxI · P(x)
frequency distribution
frequency measurement of various outcomes
inner fence
ut-off values for upper and lower outliers in a dataset
mean
A statistical measurement also known as the average
median
the value separating the higher half from the lower half of a data sample,
mode
the number that occurs the most in a number set
outer fence
start with the IQR and multiply this number by 3. We then subtract this number from the first quartile and add it to the third quartile. These two numbers are our outer fences.
outlier
an observation that lies an abnormal distance from other values in a random sample from a population
quartile
1 of 4 equal groups in the distribution of a number set
range
Difference between the largest and smallest values in a number set
rank
the data transformation in which numerical or ordinal values are replaced by their rank when the data are sorted.
sample space
the set of all possible outcomes or results of that experiment.
standard deviation
a measure of the amount of variation or dispersion of a set of values. The square root of variance
stem and leaf plot
a technique used to classify either discrete or continuous variables. A stem and leaf plot is used to organize data as they are collected. A stem and leaf plot looks something like a bar graph. Each number in the data is broken down into a stem and a leaf, thus the name.
variance
How far a set of random numbers are spead out from the mean
weighted average
An average of numbers using probabilities for each event as a weighting
