Worked Solution & Example Answer:The table shows the number of males in different age groups with raised cholesterol levels in Scotland between 2004 and 2013 - Scottish Highers Human Biology - Question 6 - 2018
Step 1
Calculate which age group had the greatest percentage decrease in the number of males with raised cholesterol levels between 2004 and 2013
Answer
To calculate the percentage decrease for each age group, use the formula:
ext{Percentage Decrease} = rac{ ext{Initial Value - Final Value}}{ ext{Initial Value}} imes 100-
Under 15: From 1 in 2004 to 1 in 2013:
- Percentage Decrease = ( \frac{1 - 1}{1} \times 100 = 0% )
-
15–44: From 33 in 2004 to 14 in 2013:
- Percentage Decrease = ( \frac{33 - 14}{33} \times 100 = \frac{19}{33} \times 100 \approx 57.58% )
-
45–64: From 236 in 2004 to 128 in 2013:
- Percentage Decrease = ( \frac{236 - 128}{236} \times 100 = \frac{108}{236} \times 100 \approx 45.76% )
-
Over 64: From 274 in 2004 to 167 in 2013:
- Percentage Decrease = ( \frac{274 - 167}{274} \times 100 = \frac{107}{274} \times 100 \approx 39.03% )
Based on the calculations, the age group 15–44 had the greatest percentage decrease of approximately 57.58%.
