Q1 is the “middle” value in the first half of the rank-ordered data set.
Q2 is the median value in the set
.
What do Q1 and Q2 represent?
A quarter
refers to one-fourth of a year and is typically expressed as Q1 for the first quarter, Q2 for the second quarter, and so forth.
Can Q1 be the same as Q2?
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. … Third quartile: 50.1% to 75% (above the median) Fourth quartile: the highest 25% of numbers.
How do you find Q1 from Q2?
Formula for Lower quartile (Q1)
= N + 1 multiplied by (1) divided by (4)
Formula for Middle quartile (Q2) = N + 1 multiplied by (2) divided by (4) Formula for Upper quartile (Q3) = N + 1 multiplied by (3) divided by (4)
How much data is between Q1 and Q2?
The first quartile (q1), or 25th percentile, is located such that 25 percent of the data lie below q1 and
75 percent
of the data lie above q1. The second quartile (q2), or 50th percentile or median, is located such that half (50 percent) of the data lie below q2 and the other half (50 percent) of the data lie above q2.
Is it possible that quartile 2 and 3 are the same?
Quartile 2, the median, is normally drawn somewhere between the left side of the box q1 and right side q3. This makes the box looking like it has 2 parts. However, if q2=q3 it will look like q2 was mistakenly forgotten because it would be drawn at the exact placement as q3.
Can the minimum and lower quartile be the same?
A box plot has a five number summary of a set of data that includes the minimum score, first quartile (lower), median, third quartile (upper) and maximum score. … In this case we get the
lower quartile same as the median in a
box and whisker plot.

What is Q1 Q2 and Q3 in math?
Quartiles divide a rank-ordered data set into four equal parts. … 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.
How do you find Q1?
Q1 is the median (the middle) of the lower half of the data, and Q3 is the median (the middle) of the upper half of the data. (3, 5, 7, 8, 9), | (11, 15, 16, 20, 21). Q1 = 7 and Q3 = 16. Step 5: Subtract Q1 from Q3.
How do you find Q2 in a data set?
Q2 is
the median of the data
. If the number of data points is even, keep the original data set. If the number of data points is odd, you will ignore the data entry used for the median from now on. The median is 102, so Q2 = 102.
How is quartile calculated?
The quartile formula helps
to divide a set of observations into 4 equal parts
. The first quartile lies in the middle of the first term and the median. The median is the second quartile. … Second Quartile(Q2) = ((n + 1)/2)
t h
Term.
What is the difference between upper and lower quartile?
the lower quartile is
the median of the lower half
of the data. The. the upper quartile is the median of the upper half of the data.
What percentage of data lies between Q1 Q3?
34Since Q1 and Q3 capture the middle 50% of the data and the median splits the data in the middle,
25%
of the data fall between Q1 and the median, and another 25% falls between the median and Q3.
