Data analysis with R is a powerful approach, making it a popular choice among statisticians and data scientists. Example of data analysis using R, utilizing a dataset of student exam scores. Firstly, we need to import the dataset into R. Assuming our dataset is in a CSV file named "scores.csv," we can use the `read.csv` function: # Read the dataset data <- read.csv("exam_scores.csv") # Display the first few rows of the dataset head(data) # Summarize the dataset summary(data) # Calculate the average score average_score <- mean(data$Score) To visualize the distribution of scores, we can create a histogram: # Create a histogram hist(data$Score, main = "Exam Score Distribution", xlab = "Score") We can create a scatter plot: # Create a scatter plot plot(data$StudyHours, data$Score, main = "Study Hours vs. Exam Score", xlab = "Study Hours", ylab = "Score") These are just the basics; R offers a wide range of packages
