User sharePopulation share
24%15%

To find

User index.

Formula and why

\text{Index}=\frac{\%\text{ users in segment}}{\%\text{ population in segment}}\times100LaTeX: \text{Index}=\frac{\%\text{ users in segment}}{\%\text{ population in segment}}\times100

Compare the group’s representation among users against its population representation.

Step-by-step solution

Step 1. Substitute the percentages

\frac{24}{15}\times100LaTeX: \frac{24}{15}\times100

Step 2. Divide

24\div15=1.6LaTeX: 24\div15=1.6

Step 3. Scale and compare

1.6\times100=160LaTeX: 1.6\times100=160

Final answer: Index = 160.
