R Fieldwork #10<\/p>\n
Database Management and Modeling<\/p>\n
General exercises<\/p>\n
Create a text vector called Months with names of the 12 months of the year. <\/p>\n
Create a numeric vector Summer, with Calendar month index positions for the summer months (inclusive, with 4 elements in all). <\/p>\n
Print out the positions to show which months they refer to.<\/p>\n
E-commerce Data for Exercises <\/p>\n
The data set comprises responses to intercept surveys asked when users visited the site, along with data about each user\u2019s site activity such as number of pages visited and whether a sale was completed. Identifying details for the site and customers have been removed but the observations otherwise are actual data. <\/p>\n
We will load the data set first, and then explain a few of its observations. To load the data from CSV format, use the following command (or load ecommerce-data.csv from a local location if you have downloaded it, as noted in Section 1.6.3). <\/p>\n
ecomm.df <- read.csv("https:\/\/goo.gl\/hzRyFd") <\/p>\n
summary(ecomm.df) <\/p>\n
How many observations and variables are in the e-commerce data set? <\/p>\n
Compute a frequency table for the country of origin for site visits. After the United States, which country had the most visitors? <\/p>\n
Compute a two-way frequency table for the intent to purchase (intentWasPlanningToBuy), broken out by user profile. <\/p>\n
What are the proportions of parents who intended to purchase? the proportions of teachers who did? For each one, omit observations for whom the intent is unknown (blank). <\/p>\n
Among US states (recorded in the variable region), which state had the most visitors and how many? <\/p>\n
Draw a histogram for the number of visits to the site (behavNumVisits). <\/p>\n
Draw a horizontal boxplot for the number of site visits. Interpret results.<\/p>\n","protected":false},"excerpt":{"rendered":"
