what is the mean, median and mode for 428, 472, 510, 386, 440?

Answer 1

Let's approach this step-by-step:

First, let's order these numbers from least to greatest:

386, 428, 440, 472, 510

Mean:

The mean is the average of all numbers.

Sum: 386 + 428 + 440 + 472 + 510 = 2236

Count: 5

Mean = 2236 ÷ 5 = 447.2

Median:

The median is the middle number when the numbers are in order.

With 5 numbers, the median is the 3rd number.

Median = 440

Mode:

The mode is the number that appears most frequently.

In this set, each number appears only once, so there is no mode.

Therefore:

Mean = 447.2

Median = 440

Mode = No mode (or the set is amodal)
