The image contains three mathematical questions in Indonesian:

1. Tentukan rata-rata hitung baik secara data tunggal maupun data kelompok

   • Translation: Determine the arithmetic mean for both single data and grouped data.

2. Tentukan rata-rata ukur

   • Translation: Determine the geometric mean.

3. Tentukan rata-rata harmonik

   • Translation: Determine the harmonic mean.

Would you like further explanations or examples on how to calculate these different types of averages?

Here are five questions to expand your understanding:

1. How do you calculate the arithmetic mean for grouped data?
2. What is the formula for calculating the geometric mean of multiple values?
3. Can the harmonic mean be used for all types of datasets? If not, why?
4. In what scenarios is it better to use the geometric mean instead of the arithmetic mean?
5. How does the harmonic mean differ in application from the arithmetic and geometric means?

Tip: The arithmetic mean is the most common average used, but the geometric and harmonic means are more suited for multiplicative or rate-related datasets.
