Final answer:
Descriptive statistics involves analyzing and summarizing data. Measures of central tendency and dispersion are used to describe the survey results.
Step-by-step explanation:
The subject of this bIn descriptive statistics, we analyze and summarize data to understand its characteristics. In this question, we are asked about the measures of central tendency and measures of dispersion that can be used to describe the survey results.
A) The mean and median are measures of central tendency. The mean is the arithmetic average of the data values, and the median is the middle value when the data is arranged in ascending or descending order.
B) The range and variance are measures of dispersion. The range is the difference between the maximum and minimum values, and the variance measures the spread of the data around the mean.
C) The mode and standard deviation are also measures of dispersion. The mode is the value that appears most frequently, and the standard deviation measures the average distance between each data point and the mean.
D) Frequency and histogram are not specific measures of central tendency or dispersion.
