SUMMARY

The discussion focuses on creating a stem and leaf plot for a dataset representing the number of dependent children in 50 families, as outlined in exercise 2.37 of "Exploring Statistics: A Modern Introduction to Data Analysis and Inference" by Larry J. Kitchens, 2nd edition. The minimum and maximum values in the dataset are 0 and 6, respectively. Participants discuss the correct format for the stem and leaf plot, emphasizing the need to categorize the data into appropriate buckets and represent the leaves accurately. The conversation highlights the challenge of implementing this method with single-digit data.

PREREQUISITES
  • Understanding of stem and leaf plot construction
  • Familiarity with data categorization techniques
  • Basic knowledge of data analysis concepts
  • Experience with the book "Exploring Statistics" by Larry J. Kitchens
NEXT STEPS
  • Research how to create stem and leaf plots with single-digit data
  • Learn about data bucketing techniques for effective visualization
  • Explore additional examples of stem and leaf plots in statistical analysis
  • Review the relevant sections in "Exploring Statistics" by Larry J. Kitchens for further insights
USEFUL FOR

Students, educators, and data analysts who are learning about data visualization techniques, specifically stem and leaf plots, and those working with small datasets in statistical analysis.

Homework Statement
The data below is the numbers of dependent children that were recorded in the 50 families' interviews. Arrange the data into an ordered stem and leaf plot.
Relevant Equations
N/a
The exercise is 2.37 in the book, Exploring Statistics: A modern introduction to data analysis and inference by Larry J. Kitchens 2nd editions.

The data is the following:
3224112341
2012104210
0130322303
2501214305
2011261215

I know the min and the max values are 0 and 6, respectively. But I am having some trouble with the stem and leave part of the plot. I don't know how to represent the data correctly...

I know that this is the right format:

StemLeaves
0
1
2
3
4
5
6
Thanks,

All I know about stem and leaf plots is from a quick search online. Looks like you normally have more digits in the each datum and pick power of 10 exponent at which to separate the stem from the leaf. It's not obvious how to implement that when you only have single digits.
At one extreme, everything is a leaf, so just list all the values in ascending order, showing repeats, in one line. At the other, everything is stem and all the leaves are just zeroes (e.g. if there are three occurrences of 4 in the data then stem 4 has three leaves, all 0.
In between, you would need to create equal sized buckets, like 0-2, 3-5, ... For a datum value n, its bucket would be b(n)=rounddown(n/3)*3 and its leaf would be n-b(n).

If you are expected to solve this question then you should have something in your notes on it.
