Quartiles for ungrouped data Calculator

  • STATISTICS
Quartiles for ungrouped data Use this calculator to find the Quartiles for ungrouped (raw) data. Quartiles Calculator for ungrouped data Enter the X Values (Separated by comma,) Calculate Results Number of Obs. (n): Ascending order of X values : First Quartile :($Q_1$) Second Quartile :($Q_2$) Third Quartile :($Q_3$) Quartiles for ungrouped data The $i^{th}$ quartile for ungrouped data is given by $ Q_i =$ Value of $\bigg(\dfrac{i(N+1)}{4}\bigg)^{th}$ observation, $i=1,2,3$ where $N$ is the total number of observations.

Mean median mode for Frequency Distribution Calculator

  • STATISTICS
Mean median Mode for Frequency Distribution Calculator The mean of frequency distribution referred to as the average. For frequency distributions, where data is grouped into intervals with corresponding frequencies, calculating the mean can be complex. The median of grouped data reprensents the middle value of a dataset. In the case of grouped data or frequency distributions, finding the median manually involves calculations. The mode of frequency distribution reprensets the value that appears most frequently in a dataset.

Deciles for ungrouped data calculator

  • STATISTICS
Deciles for ungrouped data calculator Use Decile calculator to find the deciles for ungrouped (raw) data. Deciles are the values of arranged data which divide whole data into ten equal parts. They are 9 in numbers namely $D_1,D_2, \cdots, D_9$. Here $D_1$ is first decile, $D_2$ is second decile, $D_3$ is third decile and so on. Formula The formula for $i^{th}$ decile is $D_i =$ Value of $\bigg(\dfrac{i(N+1)}{10}\bigg)^{th}$ observation, $i=1,2,3,\cdots, 7$ where $N$ is the total number of observations.
