Questions & Answers

Q: What are the advantages of using R for data science?

R is a free and open-source language with a large community and extensive package ecosystem. It offers powerful tools for data analysis, visualization, and statistical modeling.

Q: How can the summary function be used to compute descriptive statistics?

The summary function provides basic statistics like count, mean, median, and quartiles for a variable. It is useful for getting a quick overview of the data.

Q: What is the purpose of a histogram?

A histogram visualizes the distribution of a quantitative variable. It shows the frequency or count of values within specific intervals, allowing for a better understanding of the data's distribution.

Q: How can scatter plots be used to analyze data?

Scatter plots show the relationship between two quantitative variables. They can indicate the presence of a linear or non-linear association, as well as the presence of outliers or gaps in the data.
