Data from representative samples of a population of brown anoles:

**Point in Time**
- **Start**: Hindlimb Length Measurements (mm): 33.0, 34.2, 34.4, 34.7, 35.0, 36.7, 37.2, 37.2
- **End**: Hindlimb Length Measurements (mm): 36.1, 37.9, 38.8, 39.9, 40.0, 40.9, 42.0, 42.0

**Average Hindlimb Length (mm):**
Calculate the average from the given measurements for both the start and end times.

Answer :

The mean value of the sample data given is : 37.5 mm

The mean of the sample can be calculated thus ;

  • ∑x / n
  • n = number of samples

Taking the sum of the data :

∑x = 600

n = 16

The mean would be ;

  • Mean = 600 / 16 = 37.5

The mean of the sample data is : 37.5
