Question

"A researcher records the time (in seconds) that participants arrive late for a scheduled research study. Assuming these data are normally distributed, which measure of central tendency is most appropriate to describe these data?"

Answer 1

Answer:

Mean is the measure of central tendency is most appropriate to describe the given data.

Step-by-step explanation:

We are given the following in the question:

The distribution of time in seconds is a bell shaped distribution that is a normal distribution.

Properties of a normal distribution:

• The mean, mode and median for a normal distribution are equal.
• The mean divides the data into two equal parts.
• The area under the graph is 1.
• Thus, mean is the most appropriate measure of central tendency for normally distributed data.

Thus, the correct answer is

Mean is the measure of central tendency is most appropriate to describe the given data.
