Learning Objectives
Under this topic, you will be required to read social studies readings and answer several questions thereafter. After interacting with this unit, learners will be asked to:
- Calculate the mean, median, mode, and range of a given data set, such as the population of counties in a state.
The mean, also known as the average, is calculated by summing up all the values in a dataset and dividing by the total number of values. It represents a central tendency of the data and is sensitive to outliers. The median is the middle value in a dataset when the values are arranged in ascending or descending order. If there is an even number of values, the median is the average of the two middle values. It is less affected by extreme values compared to the mean and provides a measure of central tendency. The mode is the value that appears most frequently in a dataset. A dataset may have one mode (unimodal), two modes (bimodal), or more than two modes (multimodal). It is useful for identifying the most common value or category in a distribution. The range is the difference between the highest and lowest values in a dataset. It provides a measure of dispersion or spread in the data. While it gives an indication of the variability within the dataset, it does not consider the distribution of values between the extremes.

- Apply statistical concepts to analyze and interpret social studies data, enabling insights into trends, patterns, and variations within a population or region.
- Utilize statistical measures to compare and contrast different aspects of social studies data, facilitating a deeper understanding of demographic, economic, or geographic factors influencing a given area or population.
