This article is about the experiment that we did with celery. The class rated the celery on a scale from 1 to 5, 1 being the best freshness and 5 being the worst. Below is our information in a table.
# | control | blue | red | | 1 | 4.5 | 22.7 | 9.1 | | 2 | 40.9 | 9.1 | 9.1 | | 3 | 18.2 | 22.7 | 18.2 | | 4 | 18.2 | 18.2 | 36.4 | | 5 | 18.2 | 27.3 | 27.3 |
#= freshness scale. Numbers are the percent of students who voted for that freshness. For example, 4.5% of the students thought their control celery should be rated a freshness of 1, while 22.7% thought the blue celery rated a 1, and 9.1% thought the red celery rated a 1. Below is the same information in a triple bar graph.
