MHB Construct a frequency distribution using 5 classes

AI Thread Summary
The discussion focuses on constructing a frequency distribution for the time spent reading a political blog, using a dataset of minutes ranging from 0 to 49. Participants suggest dividing the data into five equal classes: 0-9, 10-19, 20-29, 30-39, and 40-49. The frequency distribution table includes calculations for frequency, midpoints, relative frequencies, and cumulative frequencies. The class with the greatest frequency is identified as 0-9, while the least frequency class is 40-49. This method effectively summarizes the reading time data into a clear distribution format.

How do you know what the classes are?

Hi rihnavy! Welcome to MHB! ;)

By dividing the range into 5 equal parts.
The minimum is 0 and the maximum is 49.
So pick 0-9, 10-19, 20-29, 30-39, 40-49.
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
