Correct option is A
Ans: (a)
Inferential statistics
Sol.
Inferential statistics involves using sample data to make predictions, inferences, or generalizations about a
population. This type of statistics allows researchers to test hypotheses, estimate population parameters, and make decisions based on sample data. Common techniques include hypothesis testing, confidence intervals, and regression analysis.
Explanation of each option:
·
(a) Inferential statistics: Correct answer. Inferential statistics uses data from a sample to draw conclusions or make generalizations about a larger population. It is the branch of statistics used to make predictions or inferences beyond the immediate data.
·
(b) Vital statistics: This refers to the collection, analysis, and interpretation of data related to births, deaths, marriage, and disease rates within a population. It is not focused on making predictions or inferences based on samples.
·
(c) Descriptive statistics: Descriptive statistics involves summarizing or describing the features of a dataset, such as mean, median, mode, and standard deviation. It does not involve making inferences or generalizations about a larger population from sample data.
·
(d) Epidemiological statistics: This refers to the study of the distribution and determinants of health-related events in populations. While it involves statistical methods, it specifically focuses on public health, diseases, and their causes, rather than predictions and generalizations about a population based on a sample.
