Math Problem Statement

The user submitted an image displaying a frequency distribution table of salaries (in millions of rupiah) and their corresponding frequencies.

Solution

The image displays a frequency distribution table of salaries (in millions of rupiah) and their corresponding frequencies. Here’s the breakdown:

  • Gaji (jutaaan rupiah): Represents salaries in millions of rupiah, ranging from 5 to 10.
  • Frekuensi: Represents the frequency or count of each salary.

The data from the table is as follows:

Gaji (jutaaan rupiah)5678910
Frekuensi123322

This table shows that:

  • 1 person earns 5 million rupiah,
  • 2 people earn 6 million rupiah,
  • 3 people earn 7 million rupiah,
  • 3 people earn 8 million rupiah,
  • 2 people earn 9 million rupiah, and
  • 2 people earn 10 million rupiah.

Do you need help calculating anything from this data, such as the mean, mode, or median salary?


Here are five related questions to expand the discussion:

  1. How do we calculate the mean salary from this table?
  2. What is the median salary and how can we find it using this data?
  3. How can we identify the mode of the salary distribution?
  4. Can we compute the range of the salaries from this data?
  5. How can we calculate the total number of individuals based on this table?

Tip: When working with frequency tables, always check the total number of observations to ensure accuracy in statistical calculations.
