Discussion Overview

The discussion revolves around how to create a histogram, specifically in the context of helping with statistics homework. Participants share their understanding and methods for constructing a histogram, including the organization of data and graphical representation.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant expresses difficulty in recalling how to make a histogram and seeks a refresher.
  • Another participant describes a histogram as a frequency chart, suggesting that the x-axis should be divided into equally-spaced segments with bars representing the number of data points in each interval.
  • A third participant provides a link to a Wikipedia article on histograms, implying it contains self-explanatory information.
  • Further, a participant outlines a step-by-step method for creating a histogram, including determining the number of bins and plotting the data accordingly.
  • One participant indicates that they now understand how to create a histogram after the discussion.

Areas of Agreement / Disagreement

Participants generally agree on the basic structure and purpose of a histogram, but there are variations in the details of the approach to creating one. No significant disagreements are noted, but the discussion remains focused on clarifying the process rather than establishing a single method as definitive.

Contextual Notes

Some steps and assumptions in the histogram creation process are not fully detailed, and the discussion does not resolve potential variations in methods or definitions of bins.

I am trying to help my brother on his Stats homework, but for the life of me, I can't rememeber how to make a histogram. He has the answers to compare to, but is unsure how they got to them, as am I. It's been so long since I have done this stuff, I need a little refresher. Google is not helping so much like it normally does, lol.

it's just a frequency chart. divide the x-axis into equally-spaced segments, and place a bar there. height of bar is number of data points that fall in that interval.
 


1. Determine how many bins you want to implement, for example, 10 bins: 1-10, 11-20, 21-30, 31-40, 41-50, 51-60, 61-70, 71-80, 81-90, 91-100.

2. Create a graph y vs x. y will be the number of times a number appears that belongs in either one of the bins. x will be the bin number starting with lowest number. (x values: 1, 11, 21, 31, 41, 51, 61, 71, 81, 91)

3. Count and fill out the graph.
 


Thanks everyone :) I think I understand it now.
