LQ = (U2 + U3)/2
and
UQ = (U6 + U7)/2
where Un is the nthnumber in the ordered setwill be sufficiently accurate.
If you want greater accuracy, you could go for
Lower quartile = U2 + 0.25*(U3-U2)Upper quartile = U6 + 0.75*(U7-U6)
But, to be honest, if you want accurate results you need more than 8 observations!

How do you find upper and lower quartile?
See related link. Upper and lower quartiles are the 75 and 25% percentile measures.
How do you find the IQR of a set of data?
Iqr stands for inter quartile range and it is used to find the middle of the quartiles in a set of data. To find this, you find the lower quartile range and the upper quartile range, and divide them both together.
How do you make a box and whiskers plot?
I personally hated these. So say you have a set of numbers. 78, 80, 81, 83 ,and 85. You need to find the lower quartile, upper quartile, and of course median. the highest and lowest points will be on the end. draw a box around the upper, and lower quartile and lines coming out from it connecting to 78 and 85.
How do you find the lower and upper quartile?
U find the upper quartile by going to ur data and finding the median by ur median and the lower or upper extreme
How do you find the inter quartile range?
Subtract the lower quartile from the upper quartile.
How do you find upper and lower quartile?
See related link. Upper and lower quartiles are the 75 and 25% percentile measures.
How do you find the lower and upper quartiles with only 5 values?
The lower quartile is the second smallest and the upper quartile is the fourth smallest (second largest).
How do you find the inner and outer quartiles?
To find the inner quartiles (Q1 and Q3), first arrange your data in ascending order. Q1 is the median of the lower half of the data, and Q3 is the median of the upper half. The inner quartiles divide the data into four equal parts. The outer quartiles also known as the minimum and maximum values, are the smallest and largest values in the data set.

Iqr stands for inter quartile range and it is used to find the middle of the quartiles in a set of data. To find this, you find the lower quartile range and the upper quartile range, and divide them both together.
What is utility of cumulative frequency curve?
The main utility of a cumulative frequency curve is to show the distribution of the data points and its skew. It can be used to find the median, the upper and lower quartiles, and the range of the data.

What is the meaning of lower class boundary in statistics?
In statistics the class boundaries are numbers that separate classes without forming gaps. To find the lower, you subtract 0.5 and to find the upper, you add 0.5. If the class is 3-7 the lower class boundary would be 2.5 and the upper 7.5. The upper boundary of one class will equal the lower boundary of the next class.
How to find the upper and lower bound of 1000?
How do you calculate the upper and lower bounds? Image result for How to find the upper and lower bound of 1000? In order to find the upper and lower bounds of a rounded number: Identify the place value of the degree of accuracy stated. Divide this place value by
How do you find the first and third quartiles?
37
How do you find the lower and upper quartile?
U find the upper quartile by going to ur data and finding the median by ur median and the lower or upper extreme
How do you find the inter-quartile of 7 numbers?
The interquartile range is the difference between the Lower quartile and the upper quartile. Obviously you need to be able to find these values. Haylock (2006) explains how to do this for difficult size groups in mathematics explained for primary teachers. He explains the position of the lower quartile is a quarter of (n+1) and that of the upper quartile is three-quarters of (n+1). So for a group of 7 numbers, you find a quarter of 8, which is 2. Therefore the number in second place is the lower quartile. Three quarters of 8 is 6 and so the number in 6th position is the upper quartile. Now take the lower quartile from the upper quartile.
How do you find the interquartile range of a data?
The Inter-quartile range is the range of the middle half of the data. It is the difference between the upper and lower quartile.Example: 35,80,100 110,120,120,170,180.The Inter-quartile range would be 145-90 or 55To find the interquartile range, you:1) Arrange the data in numerical order.2) Then find the median of the data sets.3) Find the median of the top half and bottom half. (of the set of numbers)4) The groups you now have are "quartiles"5) Find the interquartile range. (subtract the smaller range from the range)
