2 Introduction

Hello, this is Burcu! I work as a senior manager at EY, Tax Technology and Transformation service line. I have a very fun and young team of 13 people. We run projects that design processes transforming our clients’ time-consuming tasks with technology. In our projects, we make extensive use of data analytics and robotic process automation tools. I believe that a Master’s program in Big Data Analytics will take my career to the next level. Learning and experiencing new tools can be challenging but also enjoyable!

Key Features:

  • Song title

  • Artist name

  • Album name

  • Song duration

  • Key

  • Tempo

  • Vocal content

  • Danceability

  • Energy level

  • Acousticness level

  • Instrumentalness level

5.1 Calculating Mean, Median, and Standard Deviation:

# Create a numeric vector
data <- c(12, 18, 25, 32, 45, 54, 63)

# Calculate the mean, median, and standard deviation
mean_value <- mean(data)
median_value <- median(data)
std_dev <- sd(data)

# Print the results
cat("Mean:", mean_value, "\n")
Mean: 35.57143 
cat("Median:", median_value, "\n")
Median: 32 
cat("Standard Deviation:", std_dev, "\n")
Standard Deviation: 19.01628 

This code calculates the mean, median, and standard deviation of a numeric vector data.

5.2 Creating and Plotting a Scatter Plot:

# Create example data
x <- c(1, 2, 3, 4, 5)
y <- c(2, 4, 6, 8, 10)

# Create a scatter plot
plot(x, y, main = "Scatter Plot Example", xlab = "X-Axis", ylab = "Y-Axis", pch = 19, col = "blue")

This code creates a simple scatter plot using the plot function.

5.3 Creating a Bar Plot:

# Sample data
categories <- c("Category A", "Category B", "Category C", "Category D")
values <- c(25, 40, 30, 50)

# Create a bar plot
barplot(values, names.arg = categories, main = "Simple Bar Plot", xlab = "Categories", ylab = "Values", col = "skyblue")

In this example, there is a vector of category names and their corresponding values. The code creates a basic bar plot using the barplot function, showing the distribution of values across the categories. You can modify the categories and values vectors to represent your own data for this bar plot.
