angie is certified plantita she decided to record the length of the leaves of 14 plants to determine the mean median and model length the length in mm are as follows 23 21 19 20 25 22 21 23 24 29 22 15 26 and 25 help and you solve for the mean median and model length

Answer:
Hey! here's the answer just double check if I made a mistake in calculating it.
To find the mean length:
1. Add up all the lengths: 23 + 21 + 19 + 20 + 25 + 22 + 21 + 23 + 24 + 29 + 22 + 15 + 26 + 25 = 290
2. Divide the sum by the total number of lengths: 290 ÷ 14 = 20.71
Therefore, the mean length of the plant leaves is approximately 20.71 mm.
To find the median length:
1. Put the lengths in order from smallest to largest: 15, 19, 20, 21, 21, 22, 22, 23, 23, 24, 25, 25, 26, 29
2. Find the middle value: the median is the value in the middle of the sorted list. In this case, there are 14 lengths, so the middle is between the 7th and 8th values.
3. Average the two middle values: (22 + 23) ÷ 2 = 22.5
Therefore, the median length of the plant leaves is approximately 22.5 mm.
To find the mode length:
1. The mode is the value that appears most frequently in the list.
2. In this case, there are two values that appear twice: 21 and 23. All other values appear only once.
3. Therefore, there are two modes: 21 mm and 23 mm.
Therefore, the mode length of the plant leaves is either 21 mm or 23 mm.
