A useful place to start
Choose the tool that matches the biological model, and verify that its assumptions fit your data.
Bacteria Growth Calculator
Estimate bacterial population after a chosen time using exponential growth rate, with doubling time, multiplier, assumptions, and microbiology limitations.
Allele Frequency Calculator
Estimate Hardy-Weinberg allele frequency and carrier frequency from recessive disease frequency, with assumptions, interpretation, and a worked example.
Basal Area Calculator
Calculate tree basal area from DBH in inches or centimeters, convert it to a per-acre or per-hectare basis, and understand what the forestry result means.
