Statistics that allow for inferences or estimates about the population. Inferential statistics enable analysts come to conclusions about the population based on sample data. Inferential statistics cover the basics of inferential statistics, all kinds of hypotheses tests and their confidence intervals, design of experiments, and statistical power and errors. It also includes point estimation techniques, limit theorems, sampling distributions, approximations, and bounds. Correlation, regression, and association are also covered under inferential statistics to infer relationships between variables.
Expert Solution & Answer
To determine
Whether the given statement uses descriptive or inferential statistics.
Answer to Problem 1.1.1RE
The given statement uses inferential statistics.
Explanation of Solution
Given info:
By 2040 at least 3.5 billion people will run short of water.
Justification:
Descriptive statistics:
Descriptive statistics analyzes and presents the data in a simpler way. The data is represented in charts, graphs or in a tabular form. It aims to organize and summarize the data rather than using data to learn about the population.
Inferential statistics:
Inferential statistics is used to predict the future values from the current population values. It makes judgment about the futures. It uses sample data from the population and makes generalization about the population.
Here, from the past and current situation of scarcity of water it is predicted that there will be shortfall for water for 3.5 billion people. The statement gives information about the future water availability in coming years. This data is predicting a scenario which is likely to happen but hasn’t happened till now.
Hence, the given statement uses inferential statistics.
