LeafHoppers

Description

Lefetimes for potato leafhoppers on various sugar diets

Format

A dataset with 8 observations on the following 2 variables.

Diet Control, Fructose, Glucose, or Sucrose
Days Number of days until half the leafhoppers in a dish died

Details

The goal of this study was to compare the effects of four diets on the lifespan of small insects called potato leafhoppers. One of the four was a control diet: just distilled water with no nutritive value. Each of the other three diets had a particular sugar added to the distilled water, one of glucose, sucrose, or fructose. Leafhoppers were sorted into groups of eight and each group was put into one of eight lab dishes. Each of the four diets was added to two dishes, chosen using chance.
