Math Problem Statement

6 numbers from 0 to 9 that have a median of 4, a mean of 4 and a mode of 3

Solution

To determine 6 numbers between 0 and 9 that meet the following criteria:

  1. Median of 4: The middle two numbers (when sorted) must average to 4, as there are 6 numbers.
  2. Mean of 4: The sum of the numbers must be 6×4=246 \times 4 = 24.
  3. Mode of 3: The number 3 must appear more often than any other number.

Step-by-step solution:

1. Median of 4

For the median to be 4, the middle two numbers (when sorted) must be either:

  • Both 4 (4+4)/2=44+4)/2 = 4, or
  • Numbers that average to 4, such as 3 and 5.

2. Mode of 3

To ensure the mode is 3, 3 must appear at least twice, preferably more.

3. Mean of 4

The total of the 6 numbers must be 2424.

Possible solution:

Consider: {3,3,4,4,5,5}\{3, 3, 4, 4, 5, 5\}

  • Median: The two middle numbers are 4 and 4. Their average is 4.
  • Mean: 3+3+4+4+5+56=246=4\frac{3+3+4+4+5+5}{6} = \frac{24}{6} = 4.
  • Mode: The number 3 appears most often (twice).

Thus, {3,3,4,4,5,5}\{3, 3, 4, 4, 5, 5\} satisfies all the criteria.

Tip:

Always verify each condition (mean, median, mode) step by step to ensure accuracy when constructing such datasets.
