Is the median greater than the first quartile?
By definition yes. The median is the number which is exactly in the middle of a set of numbers. The first quartile is the point where 25% of the numbers are to the left, and 75% of the numbers are to the right.
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.
What is the median of the lower half of a set of numbers?
The lower quartile.
How do you calculate first and third quartile?
first quartile (Q1) : Total number of term(N)/4 = Nth term third quartile (Q3): 3 x (N)/4th term
The first quartile of a data set is 32 and the third quartile is 52. Which of these values in the data set is an outlier?
83

What is a quartile?
values that divide a list of numbers into quaters is called a quartile.
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.
How do you find the upper and lower quartile for a histogram with unequal class widths?

What is the difference between the first and third quartile?
The first quartile, or the lower quartile, is the value such that a quarter of the observations are smaller and three quarters are larger.The third quartile, or the upper quartile, is the value such that three quarters of the observations are smaller and a quarter are larger.
What is the interquartile range of a number?
the IQR is the third quartile minus the first quartile.
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 upper quartile of the numbers 75 80 85 90 95 100 105 110 115 120 125 130 135?
To find the upper quartile (Q3) of the dataset, first, arrange the numbers in ascending order, which they already are. The upper quartile is the median of the upper half of the data. In this case, the upper half consists of the numbers 110, 115, 120, 125, 130, 135. The median of these values is the average of the third and fourth numbers (120 and 125), which is (120 + 125) / 2 = 122.5. Thus, the upper quartile is 122.5.
What percent of the observations in a distribution lie between the first quartile and the third quartile?
50%
What is the median of the lower half of a set of numbers?
The lower quartile.
What is a 5- number summary?
A Five number summary is the minimum, quartile 1, median, quartile 3, and maximum of the data. (numbers)
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.
