What is the name for the difference between the third quartile and first quartile in a five number summary?
interquartile range or IQR
What percent of the observations in a distribution lie between the first quartile and the third quartile?
50%
How do you calculate the third quartile for a mean of 110 and a standard deviation of 15?
If this is the only information you have, the answer would be somewhere around 125. Usually, you would find the third quartile by first finding the median. Then find the median of all of the numbers between the median and the largest number, which is the third quartile.
What is the first quartile of this data set 6 47 49 15 43 41 7 36?
The first quartile is the value such that a quarter of the data are smaller than that value and three quarters are larger. Since there are 8 observations, the quartile will be between the second and the third smallest values. Therefore, Q1 = (7+15)/2 = 11
Find the first and third quartiles Q1 and Q3 what set of numbers 347 242 146 391 249 567 277 218 319?
242 is the first quartile. 347 is the third quartile.

Interquartile range.
What is the name for the difference between the first quartile and the third quartile in a five number summary?
75th percentile
What is the name for the difference between the third quartile and first quartile in a five number summary?
interquartile range or IQR
What is the name of the difference between the third and the first quartile?
Interquartile range denoted IQR.
What is the name of the difference between the third quartile and first quartile in five number summary?
The difference between the third quartile (Q3) and the first quartile (Q1) in a five-number summary is called the interquartile range (IQR). It represents the range of the middle 50% of the data, providing a measure of statistical dispersion. The IQR is useful for identifying outliers and understanding the spread of the dataset.
What percent of the observations in a distribution lie between the first quartile and the third quartile?
50%
In which area of calculation quartile deviation is used?
Graphing to determine difference between third and first quartile as well as to find the median between the two. Also known as semi-interquartile range.
What is the difference between a percentile and a quartile?
A quartile divides a grouping into four. The first quartile will have the first 25% of the group, the second quartile will have the second 25% of the group, the third quartile will have the third 25% of the group and the last quartile will have the last 25% of the group. For example if a classroom had 20 students who had all taken a test, you could line them up, the top 5 marks would be in the first quartile, the next five would be in the second quartile, the next 5 would be in the third quartile, and the 5 students with the lowest marks would be in the last quartile. Similarly, a percentile divides a grouping, except the group is divided into 100. Each 1% represent 1 percentile.

What is the distance between 67.8 and 70.8 on a box plot?
The distance between 67.8 and 70.8 on a box plot is known as the interquartile range (IQR). It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1), which represent the limits of the box in the box plot.
What is the interquartile range of a number?
the IQR is the third quartile minus the first quartile.
