Chapter 4

Question 1

Sampling distribution

Answer 1

the probability distribution of all the values for an estimate that we might have obtained when we sampled the population

Question 2

Standard error

Answer 2

the SD of the estimate’s sampling distribution; measures precision of an estimate

Question 3

Confidence interval

Answer 3

range of values surrounding the sample estimate that is likely to contain the population parameter

Question 4

Sample means vary less with (larger/smaller) samples.

Answer 4

Larger

Question 5

Can larger samples fix bias?

Answer 5

No

Question 6

Pseudoreplication

Answer 6

error that occurs when samples are not independent but are treated as if they are; most common fault in design and analysis of ecological field experiments, leads to sample measures being more similar; high level of replication, high confidence in results
