How do you find the quartiles of a data set?
First arrange the data set in ascending order. Suppose the data set consists of n observations. the index for the lower quartile is (n + 1)/4 and the index for the upper quartile is 3*(n + 1)/4. Find the values that correspond to the number in these positions in the ordered list. For example, if n = 15, then lower index = 4 and upper index = 12. So the lower quartile is the fourth number and the upper quartile is the twelfth. If n is large, you may skip the +1 and just look at n/4 and 3n/4. Often the indices are not integers. Then, if you are a beginner (nd the fact that you asked this question suggests that you are), find the nearest whole numbers for the two indices. Otherwise you need to interpolate and that is a whole new ball game!
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 do you find the upper and lower quartile for a histogram with unequal class widths?
You would first need to know the amounts of each quartile. Then use your formula to place the numbers inside.
Find the range of the set of numbers?
Find the minimum and maximum values from the given data. Then range is the difference between maximum and minimum values.
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.
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.
What are quartiles in relationship to mean median mode?
Quartiles are values that divide a sample of data into four groups containing the same number of observations. You will find details in the related link.
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.
How do find lower and upper extreme?
To find the lower extreme, you need to identify the smallest value in a data set. To find the upper extreme, you need to identify the largest value in the data set. These values represent the lowest and highest points of the data distribution.
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 to interpert upper and lower river gauges?
You can find more information on how to interpret upper and lower river gauges on or.water.usgs.gov
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.
