Is there any relationship among quartiles deciles and percentiles explain your answer?
Similar to deciles, quartiles are a form of percentiles. While deciles split the data into 10 buckets, quartiles split them into quarters
What is the relationship between percentiles and deciles?
Deciles are similar to Percentiles (sounds like decimal and percentile together), as they split the data into 10% groups: The 1st decile is the 10th percentile (the value that divides the data so 10% is below it) The 2nd decile is the 20th percentile (the value that divides the data so 20% is below it) etc!
What is the relationship between the quartiles and the median?
The lower quartile, or first quartile, is denoted as Q1 and is the middle number that falls between the smallest value of the dataset and the median. The second quartile, Q2, is also the median.

What is a percentile quizlet?

Is 2nd quartile 50th percentile and the median always the same in value?
Quartile has two meanings, it can be one fourth of the data, or it can be a point that divides the data into quarters. By the first definition, the second quartile is everything between the 25th percentile and the median, so it’s not the same as the median.
How are the median and the second quartile related?
The second quartile, Q2, is also the median. The upper or third quartile, denoted as Q3, is the central point that lies between the median and the highest number of the distribution. First quartile: the lowest 25% of numbers. Second quartile: between 0% and 50% (up to the median)
What is the relationship between second quartile median 5th decile and 50th percentile?
Answer: It is fundamental concept that Median, second quartile, 5th decile and 50th percentile are same.
What is the relation between 50th percentile and the median?
The median is the value where fifty percent or the data values fall at or below it. Therefore, the median is the 50th percentile.
Are percentiles specific quartiles?
Quartiles are special percentiles. The first quartile, Q1 , is the same as the 25 th percentile, and the third quartile, Q3 , is the same as the 75 th percentile. The median, M , is called both the second quartile and the 50 th percentile.
