After reviewing a quality report… administrator decided to implement a new initiative to improve communication… using inferential statistics. How is the inferential statistic applied?

Determining the median is a descriptive statistic that summarizes data by identifying the middle value in a dataset. While it provides useful information about the central tendency of a dataset, it does not involve making inferences or predictions about a larger population, which is the essence of inferential statistics.

Calculating variance measures the dispersion of data points in a dataset relative to the mean. Although variance is important for understanding data variability, it does not provide insights into relationships between variables or facilitate predictions, which are central to inferential statistical methods.

Constructing a normal distribution involves creating a probability distribution that depicts how data points are spread around the mean. While this can help in understanding data behaviors, it does not directly apply inferential techniques to draw conclusions or make predictions based on sample data.
