Data Science & Visualization
This is any kind of information.
What is data?
This type of data can be quantified, measured, and expressed using numbers
What is quantitative data?
This function displays text to the console
What is print?
This function selects variables from a data frame
What is select?
This function initializes a ggplot2 plot.
What is ggplot?
This field uses scientific methods to extract insights from data
What is data science?
This type of data is non-numerical. It is expressed using attributes and categories
What is qualitative data?
This function repeats the values in an object?
What is rep?
This function creates new variables or updates existing variables from a data frame
What is mutate?
This function maps data to points on the plot.
What is geom_point?
This field involves teaching a computer how to do something without being explicitly programmed to do so?
What is machine learning?
This level of measurement corresponds to unordered categorical data
What is nominal data?
This occurs when values of different types are put together in a vector?
What is type coercion?
This group of functions combines two data frame into a single data frame
What are join functions?
This is the visual properties that you see on the plot
What are aesthetics?
Explaining, exploring, and analyzing are three functions of this
What are visualizations?
This level of measurement corresponds to ordered categorical data
What is ordinal data?
This occurs when operations on different length vectors are performed?
This occurs when operations on different length vectors are performed?
This function splits a data frame into groups before applying an operation?
What is group_by?
This function draws bars where the bars represent the value of a quantitative variable?
What is geom_col?
This is the practice of communicating insights from data and visualizations as a narrative.
What is data storytelling?
This type of data has a set of fixed and unique levels?
What is a factor?
This operator is used to check if a value is present in a vector?
What is %in%?
This function creates a new variable based on multiple conditions
What is case_when?
This maps the data to visual properties of the plot.
What are scales?
