Spreadsheets are a basic tool for organizing and analyzing data. They allow users to sort data into logical order, filter out unwanted values, and visualize data through graphs and charts. This helps users gain insights from datasets by orienting themselves to extremes, focusing on relevant values, and understanding trends in a graphical format rather than just numbers. The document demonstrates these spreadsheet functions through examples to show how they are commonly used to wrangle and better understand data.

2. Introduction
● The most basic tool used for data wrangling is a spreadsheet.
● structured, machine-readable data format.
● total, the average, different mathematical function.
● bulk processes, pulling out different graphs and charts.

3. Spreadsheets: An Overview
A variety of spreadsheet programs and applications exist

4. Sorting
● The first thing to do when looking at a new dataset is to orient
yourself.
● This involves at looking at maximum/minimum values and sorting the
data so it makes sense.

6. Filtering Data
● The next thing commonly done with datasets is to filter out the values

8. Data Visualization
● Data visualization is not just about making what you found look good
– often it is a way of gaining insight into the data
● We just understand graphical information on a better level than we
understand numbers and tables.
