The four statistical questions that need a detailed answer are: What is the mean? What is the median? What is the mode? What is the standard deviation?
Answering these four statistical questions provides a comprehensive understanding of the data set and allows for accurate interpretation and analysis.
The mean is calculated by adding all the values in a data set and dividing by the number of values. The median is the middle value in a data set when arranged in ascending or descending order. The mode is the most frequently occurring value in a data set. The standard deviation is calculated by finding the square root of the variance, which is the average of the squared differences from the mean.
The mean, median, mode, and standard deviation provide different measures of central tendency and variability in a data set. The mean gives the average value, the median gives the middle value, the mode gives the most frequently occurring value, and the standard deviation gives the spread of the data around the mean.
The answers to these four statistical questions can help us understand the characteristics of a data set and make comparisons between different data sets. This information can be used to make informed decisions in various fields such as business, medicine, and social sciences.
