Question

If value of first quartile is 49
and value of third quartile is
60 then value of inter
quartile range is
Select one:
a. 41
O b.31
c. 21
d. 11​

Answer 1

Answer:

11

Explanation:

GIVEN-If value of first quartile is 49 and value of third quartile is 60 .

TO FIND- value of third quartile

SOLUTION-

The interquartile range (IQR) measures the spread of the middle half of your data. It is the range for the middle 50% of your sample. Us the IQR to assess the variability where most of your values lie. Larger values indicate that the central portion of your data spread out further. Conversely, smaller values show that the middle values cluster more tightly.

Answer 2

Answer:

Concept:

In statistics, a quartile is a specific kind of quantile that splits the total number of data points into four roughly equal portions, or quarters. Quartiles are a type of order statistic since they require the data to be arranged from smallest to largest in order to be computed. The three quartiles mentioned above offer a five-number summary of the data along with the minimum & maximum of the data (which are also quartiles). Because it describes both the center and the distribution of the data, this summary is significant in statistics. The size of the spread and the skewedness of the dataset can be determined by knowing the lower and upper quartiles.

Given:

If the first quartile value is 49 and the third quartile value is 60, the interquartile range is

Find the correct option for the given question

Answer:

The answer is option (d). 11

The difference between the third and the very first quartile is defined by the interquartile range. The partitioned values known as quartiles divide the entire series into four equally sized segments. There are so three quartiles. Q1 denotes the first quartile, also referred as the lower quartile, Q2 the second quartile, also known as the upper quartile, and Q3 the third quartile. The lower quartile less the upper quartile equals the interquartile range. The measures of dispersion are known as the semi-interquartile range. Half of the interquartile range is often referred to as the semi interquartile range. Half of the difference between both the 75th percentile (Q3) and the 25th percentile is used to calculate it (Q1).
