SUMMARY

The discussion centers on the appropriateness of using scatter plots versus line graphs for presenting pollution index data in ecology coursework. The user received feedback indicating that a line graph was preferred, despite the data being better suited for a scatter plot. Key considerations include whether interpolation between data points was expected and if the average pollution index should be calculated as a continuous function. The confusion arose from unclear feedback from the marker regarding the expectations for data presentation.

PREREQUISITES
  • Understanding of scatter plots and line graphs in data visualization
  • Familiarity with pollution index metrics and their calculation
  • Knowledge of data interpolation techniques
  • Basic principles of statistical analysis, including least squares fitting
NEXT STEPS
  • Research best practices for using scatter plots in ecological data presentation
  • Learn about data interpolation methods and their applications
  • Explore statistical techniques for fitting lines to data, such as least squares regression
  • Investigate guidelines for effective data visualization in scientific reports
USEFUL FOR

Ecology students, data analysts, and researchers involved in environmental studies who need to effectively present and interpret pollution index data.

[SOLVED] Simple graph presentation

Forgive my not using the thread template but it doesn't really fit my problem.

I got some ecology coursework back where I had to use a few graphs to present my data. In some of the graphs I had to present scatter plots with results from a pollution index (a score based on presence/absence of various species with different pollution tolerances) at several sites against total number of species observed there. I was marked down for plotting points rather than a line. If this was say pollution index vs distance down stream fair enough, but I'm sure a line graph would be unsuitable for my data.

Was my marker having a bad day, or am I being really stupid?

The applicable questions seem to be: 1. were you expected to interpolate between data points? or 2. were you expected to calculate the average index value as a continuous function of the number of species (e.g, by fitting a least squares line)?
 
That's probably it. It just wasn't clear from her comments. Thanks.

This is [solved] but I'm not getting the option under thread tools.
