FAQs on PPT - Measures of Dispersion - Economics for A Level

1. What is the definition of measures of dispersion in commerce?
Ans. Measures of dispersion in commerce refer to statistical measures that help assess the extent of variability or spread of data points within a dataset. They provide insights into how individual values deviate from the central tendency, such as the mean or median.
2. What are the commonly used measures of dispersion in commerce?
Ans. The commonly used measures of dispersion in commerce include range, variance, standard deviation, coefficient of variation, and interquartile range. Each measure offers a different perspective on the spread of data points and is applicable in various scenarios.
3. How is range calculated as a measure of dispersion in commerce?
Ans. Range is calculated by subtracting the smallest value in a dataset from the largest value. It provides a simple measure of the overall spread of data points but does not consider the distribution within the dataset. Range is sensitive to outliers and extreme values.
4. What does standard deviation indicate in measures of dispersion in commerce?
Ans. Standard deviation is a widely used measure of dispersion in commerce. It quantifies the average amount by which data points deviate from the mean. A higher standard deviation suggests a greater spread, while a lower standard deviation indicates less variability around the mean.
5. How can measures of dispersion be useful in commerce?
Ans. Measures of dispersion are essential in commerce as they provide valuable insights into the variability of data. They help in risk assessment, decision-making, and evaluating the performance of products or services. Understanding the spread of data points allows businesses to identify trends, outliers, and potential areas of improvement or concern.
