Question 1

Explain primary vs secondary research articles

Answer 1

Primary = experiment conducted, includes method section, results

Secondary = sources only

Question 2

Describe how to use a chi-square test

Answer 2

1. Calculate frequency of p and q
2. Check HWE (usually slight deviation), record expected
   
   • Null hypothesis: the fish are in HWE
   • Alternative hypothesis: the fish are not in HWE
3. Chi-analysis
   
   1. x² = (O-E)^2 / E
   2. Degree of freedom = n - 1 (n = number of subjects)

Question 3

F_ST equations

Answer 3

F_ST = 1 - H_S/H_T

H_S = 2p1q1 + 2p2q2 / 2

H_T = 2p_Tq_T
