First, Data Collection and Management: find a site that has reviews. You can use a movie's reviews, a restaurant's reviews, a product's reviews. Some sites I have used include: Rotten Tomatoes for movies, Yelp for restaurants, Amazon for products. Your sample set doesn't need to be random, just pick given the criteria below.
Criteria for your reviews sample set are:
1. Must have at least 10.
2. Each reviews must be lengthy in text. (the longer the better).
3. Pick 9 reviews what are very favorable, and 1 that is not favorable at all. Note which one is the not favorable review. You will see why later.
Second, configure your sample data in an xls spreadsheet. This will be time consuming because a simple copy paste will include junk code that will hinder your data configuration. Hint: Copy your review text onto a .txt notepad or word, and take out everything that's not a text sentence structure ( take out paragraph breaks. You can include sentence punctuations) so your review is one big text block. Like below. I did this example with Rotten Tomatoes critic's reviews of HBO's reboot of Westworld.
