Question

B) descriptive statistical method
C) intuitive statistical method
D) inferential statistical method

Answer 1

Answer:

Correct option is (B) descriptive statistical method

Step-by-step explanation:

Descriptive statistics branch in statistics deals with the representation of the data using distinct brief coefficients. These coefficients are used as either the representative of the sample or the population.

The descriptive statistics branch is divided into two sub branches:

1. Measure of central tendency
2. Measure of dispersion.

The three measures of central tendency are:

• Mean (or Average)
• Median
• Mode.

The measures of dispersion are:

• Variance
• Standard deviation
• Range
• Kurtosis
• Skewness

The education researcher computes the average number of hours student study at various local colleges.

The average of a data is the mean value which is the measure of central tendency.

Thus, the researcher is using descriptive statistical method to summarize the data.
