Table 1 shows the heights of 5 sunflower seedlings grown under identical greenhouse conditions for 14 days.

Based on the data in Table 1, match each statistical measure of seedling height to its correct calculated value.

Mean corresponds to

16\text{ cm}

, Median corresponds to

15\text{ cm}

, and Range corresponds to

8\text{ cm}

The mean height is the average value (

16\text{ cm}

), the median height is the middle value when the dataset is ordered (

15\text{ cm}

), and the range is the difference between the highest and lowest values (

8\text{ cm}

Calculate the mean of the seedling heights.

16\text{ cm}

Sum the heights of all 5 seedlings (

12 + 15 + 18 + 15 + 20 = 80\text{ cm}

) and divide by the total number of seedlings (

5

) to obtain the arithmetic average:

\frac{80}{5} = 16\text{ cm}

Determine the median of the seedling heights.

15\text{ cm}

Order the heights from least to greatest:

12, 15, 15, 18, 20

. The median is the middle value in this list, which is the third value (

15\text{ cm}

Calculate the range of the seedling heights.

8\text{ cm}

Identify the maximum height (

20\text{ cm}

) and the minimum height (

12\text{ cm}

). Subtract the minimum from the maximum to find the range:

20 - 12 = 8\text{ cm}
