Which data would be best analyzed and communicated using a histogram?
1) the daily high temperature at a woodland weather station, measured every day for a year
2) counts for nine different species of duck sighted on a given date
3) the relative percentages of plant spores found in a sample of 10,000–year–old lake muck
4) the average number of clams dredged up at different depth ranges (5–10 m, 10–15 m, etc.)
