Stats box plot:
For finding the statistical related results there are various ways, but the box and whisker plot gives the more accurate results. In box-and-whisker plot, the interior box represents the values from the lower to upper quartile.
Steps for stats box plots online tutoring :
Step 1: The first step is to sort out the given data.
Step 2: The second step involves find the median (Q2) entire data, if there should be two middle numbers means find the mean value, it should be the median..
Step 3: Find the upper quartile and lower quartile.
Step 4: Find Q1 and Q3 percentiles.
Step 5: Find the lower most and upper most value.
Step 6: Mark the positions of Q1 , Q2 and Q3 percentiles in the grid.
Step 7: Draw a box from lower to upper quartile through Q2.
Step 8: Draw a line from lower to higher range.
Example for stats box plots online tutoring:
Draw a stats box plots for the given data
Quality : 10, 20, 90, 20, 15, 80, 25
Quantity : 20, 30, 55, 65, 90, 105, 70
Solution given by online tutoring is as follows
Sort out the data in ascending order.
Quality : 10, 15, 20, 20, 25, 80, 90
Quantity : 20, 30, 55, 65, 70, 90, 105
Median :
In the two kinds of data there are 7 information, it is odd
Therefore,
Median (Quality) Q2 = 20.
Median (Quantity) Q2= 65
Lower Median(Q1)
Quality : 10, 15, 20, 20, 25, 80, 90
Quantity : 20, 30, 55, 65, 70, 90, 105
Lower three numbers are
Quality : 10, 15, 20
Quantity : 20, 30, 55
Middle (Quality) Q1= 15
Middle (Quality) Q1= 30
Upper Median
1, 8, 9, 17, 21, 22, 23
Upper three numbers are
Quality : 10, 15, 20, 20, 25, 80, 90
Quantity : 20, 30, 55, 65, 70, 90, 105
Upper three numbers are
Quality : 25, 80, 90
Quantity : 70, 90, 105
Middle (Quality) Q3= 80
Middle (Quantity) Q3 = 90
Maximum
Quality : 10, 15, 20, 20, 25, 80, 90
Quantity : 20, 30, 55, 65, 70, 90, 105
Maximum (Quality) = 90
Maximum (Quantity) =105
Minimum
Quality : 10, 15, 20, 20, 25, 80, 90
Quantity : 20, 30, 55, 65, 70, 90, 105
In the given data 23 is the highest value.
Minimum (Quality) = 10
Minimum (Quantity) =20
