The image contains a set of mathematical tasks. Here's the breakdown of the questions:

1. Task 1: Create a pie chart and bar graph based on the given table of scores ("arvosana") and their frequencies.
2. Task 2: Calculate:
   • Relative frequencies of the scores,
   • Cumulative frequencies,
   • Relative cumulative frequencies.
3. Task 3: For the given dataset of numbers, compute:
   • Mean (keskiarvo),
   • Mode (moodi),
   • Median (mediaani).
4. Task 4: Calculate for Task 1 scores:
   • Mean,
   • Median,
   • Mode,
   • Standard deviation (keskihajonta).

Would you like me to solve all of these tasks, or focus on a specific one? Let me know if you'd like detailed graphs or explanations for any part!

Here are five related questions to expand understanding:

1. What is the difference between relative and cumulative frequencies?
2. How is the pie chart constructed using relative frequencies?
3. Why is the standard deviation useful in analyzing data?
4. What methods can be used to quickly find the median of a dataset?
5. How does the mode help in understanding the most frequent value in a dataset?

Tip: Use spreadsheet software like Excel or Google Sheets for quick graphing and calculations of cumulative/relative frequencies.
