difference and is suitable for a scale that is nominal.

Response:

  • The measure of central tendency to use is the <u>mode</u>.

<h3>How can the appropriate measure of central tendency be selected?</h3>

The mean is the sum of the measurements divided by the number count

of the plants.

The mode is the measurement that has the highest frequency.

The median is the measurement of the middle plant when arranged in a

given order according to size.

To argue that there is a difference between the plants, the measure of

central tendency to use is the mode, given that the data involves

measurements which can be expressed in a nominal scale.

Therefore;

Answer:

The solution of (-8)^{2} is 64.

Step-by-step explanation:

In Mathematics when two negative numbers are multiplied the result is a positive number, i.e. -a\times-b=ab.
