True or False, to find the interquartile range, it is the Upper quartile - the minimum number? *

1 answer:

4 0

True ..

You can also use this formula instead..

The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively.
Q1 is the “middle” value in the first half of the rank-ordered data set.
Q2 is the median value in the set.
Q3 is the “middle” value in the second half of the rank-ordered data set.
The formula for inter-quartile range is given below

IQR=Q3−Q1

Where,
IQR=Inter-quartile range
Q1 = First quartile
Q3 = Third quartile

Q1 can also be found by using the following formula

Q1=(n+14)thterm

Q3 can also be found by using the following formula:

Q3=(3(n+1)4)thterm

In these cases, if the values are not whole number, we have to round them up to the nearest integer.

Q2 can also be found by using the following formula:

Q2 = Q3 – Q1

Which is equivalent to median.

How do you use a number line from least to greatest

Arlecino [84]

Step-by-step explanation:

left to right.

the smallest numbers are on the left, the largest in the right.

all the numbers in the line are sorted.

so, going from left to right the numbers get continuously larger (no exception), and when going from right to left, they get continuously smaller.

remember that the negative numbers are smaller than the positive numbers. so, the negative numbers (if there are any in your case) are on the left side.

and negative numbers get smaller by "seemingly increasing" : -1 is larger than -2 and so on.

so, the range of the negative numbers starts on the left side with the "largest" negative number (but when you think about it, it IS the smallest number) and their absolute value gets smaller until they reach 0, and then the positive numbers start from small to large.

this also asked to fractions and mixed fraction numbers :

e.g. -2 1/2 is smaller than -2 and larger than -3.

because it is -2 + -1/2 = -2 - 1/2 = -2 1/2.

in that sense it is the same principle as with positive numbers :

2 1/2 = 2 + 1/2

-2 1/2 = -2 - 1/2
