1970 3.25
1975 3.25
1980 3.66
1985 3.83
1990 4.57
1995 4.52
2000 4.74
2005 4.69
2010 4.44

Explanation:

Step1: Order data (already sorted)

Data: $3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44$
First sort ascending: $3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74$

Step2: Calculate median (middle value)

Median = 5th value: $4.44$

Step3: Sum all data points

Sum = $3.25+3.25+3.66+3.83+4.44+4.52+4.57+4.69+4.74 = 36.95$

Step4: Compute mean (sum/number of data)

Mean = $\frac{36.95}{9} \approx 4.11$

Answer:

Median = $4.44$
Mean = $4.11$
