What a quartile?
quartile- one of the values of a variable that divides the distribution of the variable into four groups having equal frequencies.
What is quartiles?
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
If a divides b and b divides a then a is equal to b?
If a divides b and b divides a then either a is equal to b or a is equal to -b. Additional note: if a divides b, there exist a p such that ap=b. and if b divides a, there exist a q such that a=bq. then ap=(bq)p=b => b(1-pq)=0 => pq=1 since b!=0 => p=q=1 or p=q=-1 => a=b or a=-b
What is the sum of proportions computed from a frequency distribution have to equal?
The sum of proportions computed from a frequency distribution must equal
What is the relationship among the mean median and mode in a symmetric distribution?
They are all equal . . . they are the same.(In an asymmetric distribution they are not equal.)
What value which divides the data into one hundred equal parts?
A percentile.
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 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 is one of the values of a variable which divides the distribution of the variables into three groups having equal frequencies?
A tertile or tercile.
What is the mid point of a frequency?
The midpoint of a frequency distribution is the value that divides the distribution into two equal parts. It is calculated by adding the lower and upper limits of a class interval and dividing the sum by 2.
What is the highest percentile rank possible?
The highest percentile rank possible is 100. This indicates that a score is higher than or equal to all other scores in a given dataset. In other words, if someone is at the 100th percentile, they are at the top of the distribution, meaning no one scored higher. Percentile ranks provide a way to understand a score's position relative to others in a group.
What divides distribution into ten groups?
Distribution is divided into ten groups through a statistical method called deciles. Deciles split a dataset into ten equal parts, where each group contains 10% of the data points. This allows for a clearer analysis of the distribution's characteristics, such as central tendency and variability, by highlighting how data is spread across different ranges. Each decile represents a specific percentile rank, providing insights into the relative standing of values within the dataset.
What is quartiles?
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
