What is quartile Name different quartiles?
A quartile is a statistical term that divides a dataset into four equal parts, each representing a quarter of the data. The three main quartiles are the first quartile (Q1), which marks the 25th percentile, the second quartile (Q2) or median, which represents the 50th percentile, and the third quartile (Q3), which corresponds to the 75th percentile. These quartiles help to summarize and analyze the distribution of data points.
What does Quartile 3 represent?
Quartile 3 (Q3) represents the value below which 75% of the data points in a dataset fall. It is a measure of the upper range of the data, indicating that 25% of the values exceed this point. Q3 is used in statistical analysis to understand the distribution and spread of data, particularly in identifying outliers and the overall shape of the data distribution.
What is the formula for quartile deviation?
(q3-q1)/2
What divides the data into four equal parts?
The data is divided into four equal parts by quartiles. The first quartile (Q1) marks the 25th percentile, the second quartile (Q2) is the median or 50th percentile, and the third quartile (Q3) represents the 75th percentile. These quartiles help to understand the distribution of the data by segmenting it into four intervals, each containing approximately 25% of the observations.
One of the values of a variable which divides the distribution of the variable into four groups having equal frequency?
A quartile divides a distribution into four equal parts, each containing 25% of the data. The first quartile (Q1) represents the value below which 25% of the data fall, the second quartile (Q2) is the median, and the third quartile (Q3) is the value below which 75% of the data fall.
What is the formula for coefficient of quartile deviation?
coefficient of quartile deviation: (Q3-Q1)/(Q3+Q1)
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
How do you do interquartile range step by step?
Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.
If q1q2q3 are three quartiles then Coefficent of quartile deviation is?
coefficient of quartile deviation is = (q3-q1)/(q3+q1)
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.
Formula of quartile deviation?

(b) To make a boxplot of a distribution you must know what?
To create a boxplot of a distribution, you must know the five-number summary, which includes the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum values of the data set. Additionally, understanding how to identify outliers and the overall range of the data is important for accurately representing the distribution. Boxplots visually summarize the central tendency, variability, and skewness of the data.
What divides the data into four equal parts?
The data is divided into four equal parts by quartiles. The first quartile (Q1) marks the 25th percentile, the second quartile (Q2) is the median or 50th percentile, and the third quartile (Q3) represents the 75th percentile. These quartiles help to understand the distribution of the data by segmenting it into four intervals, each containing approximately 25% of the observations.
What is quartiles?
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
