Answer:
Descriptive statistic is to inferential statistic as "central tendency" is to "variability."
Explanation:
Descriptive statistics and inferential statistics are two branches of statistics that serve different purposes.
Descriptive statistics involves the collection, organization, and presentation of data in order to summarize and describe its main features. It focuses on measures of central tendency, such as the mean (average), median (middle value), and mode (most frequent value), as well as measures of variability, such as the range and standard deviation. Descriptive statistics provide a concise and informative summary of the data at hand.
On the other hand, inferential statistics is concerned with making inferences and drawing conclusions about a larger population based on a sample of data. It involves analyzing the sample data and using it to make predictions, estimate parameters, or test hypotheses about the population. Inferential statistics utilizes techniques such as hypothesis testing, confidence intervals, and regression analysis to make these inferences.
Drawing a parallel, the relationship between descriptive statistics and inferential statistics can be compared to the relationship between "central tendency" and "variability." Central tendency refers to measures that provide a representative value for the data, such as the mean or median. It gives us an idea of the typical or average value. Variability, on the other hand, refers to the spread or dispersion of the data points around the central tendency. Measures of variability, such as the range or standard deviation, quantify how much the data values deviate from the central tendency.
In summary, descriptive statistics focuses on summarizing and describing data, while inferential statistics involves making inferences and drawing conclusions about a larger population based on a sample. Central tendency measures summarize the typical value of the data, while variability measures describe the spread or dispersion of the data points around the central tendency.
