Step-by-step explanation:

1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.

Step 2: Find the median.

1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.

Step 3: Place parentheses around the numbers above and below the median.

Not necessary statistically, but it makes Q1 and Q3 easier to spot.

(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).

Step 4: Find Q1 and Q3

Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.

(1, 2, 5, 6, 7),  9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.

Step 5: Subtract Q1 from Q3 to find the interquartile range.

18 – 5 = 13.

Answer:

The value of  Q₃ = 43

Step-by-step explanation:

Given,

The first quartile (Q₁) = 23

Interquartile  range = 20

To find,

The value of the third quartile(Q₃)

Solution:

The interquartile range is the difference between the first and third quartiles.

The quartiles of data in statistics are the set of three values that divides the data into four equal parts

The first quartile is that point in a data such that 25% of the data points lie below it and 75% of the data points lie above it when the data points are arranged in ascending order

The third quartile is that point in data such that 75% of the data points lie below it and 25% of the data points lie above it when the data points are arranged in ascending order.

We have,

Interquartile range = third quartile - first quartile

Interquartile range  = Q₃ -  Q₁

Substituting the given values, we get

20 = Q₃ -  23

Q₃ = 20+23

=43

∴ The value of  Q₃ = 43
