Reasoning with Data
From Quantitative Problem Solving in Natural Resources by Peter Moore
Concepts
- Representative Samples
"Natural resource systems are often too large, numerous, or complex to measure completely, so researchers use a smaller sample to characterize the whole. A random sample is generally preferred because
- Mark-recapture Estimate
"In mark-recapture, individuals are captured, marked, released, and later captured again. The proportion of marked individuals in the second sample is used to estimate the proportion of the total popu
- Mean Median
"The mean is the arithmetic average, the median is the middle value of an ordered dataset, and the mode is the value or range occurring most frequently. The mean is sensitive to outliers, while the me
- Spread Uncertainty
"Variance and standard deviation describe how far observations typically lie from the mean, with standard deviation expressed in the same units as the original measurements. Measurement uncertainty ma
- Distributions Reveal
"A histogram displays the frequency distribution of measurements by showing how many observations fall within each bin. Uniform distributions give roughly equal frequencies across a range, while sums
