1. Q10: Temperature Coefficient
The factor by which the rate (R) of a reaction increases for every 10-degree rise in the temperature (T)
Temperature sensitivity of a reaction or process
You will often see rate of reaction symbolized as (k)
Most commonly used to compare the rate of metabolism in organisms with increasing temperature
Most, not all, biological Q10 values are between 2 and 3

2. Helpful video (Yes… Its the Bozeman Guy)!:

3. Data taken to determine the effect of temperature on the rate of respiration in a goldfish is given in the table below. Calculate Q10 for this data. Round to the nearest whole number.
Temperature (C)
Respiration Rate
(Minute) 16 21 22

4. Standard Error of the Mean
Standard Error of the Mean (SEM)
Accounts for both sample size and variability
Used to represent uncertainty in an estimate of a mean
As SE grows smaller, the likelihood that the sample mean is an accurate estimate of the population mean increases

5. Calculating Standard Error
Using the same data from our Standard Deviation calculation on your handout:
Mean =
S =
n =
SEX = =
This means the measurements vary by ± from the mean.
