What is metadata?
Data that is about the data.
Data that is everywhere.
Data that can change.
Data that needs filtered.
Recognizing patterns and similarities in data visualizations relates to which of the following about the data?
Causation
Correlation
Metadata
Filtering
Which of the following is NOT a benefit of metadata?
It can be changed without impacting the primary data
Used for sorting and filtering information
Increases effective use of data by providing extra information
Increases search speeds of the database
Which of the following is NOT a reason for data to be cleaned?
Data is incomplete
Data is invalid
Multiple tables are combined into one
Data is a string
What is the goal of the data analysis process?
To search through databases quicker
To gain insight into new information
To make sure datasets are clean
To collect the correct information
The mayor of a city is interested in learning what goals are most important for residents of the city. Members of her staff visit one of the many neighborhoods in the city and ask 20 residents to fill out a survey. The mayor is concerned that the survey may be biased and not accurately reflect the overall interests in her town. Which of the following strategies is MOST likely to address concerns about the data being biased or inaccurate
Finding the same people surveyed previously to ask more detailed questions.
Visiting the same neighborhood to collect more survey responses
Visiting multiple new neighborhoods to collect more survey responses
Having her staff collect the data using an app rather than paper surveys
In which of the following situations would parallel systems MOST likely be used to help analyze data?
Data analysis involving two or more columns of data
Data analysis involving both string and numeric data
Data analysis involving large datasets
Data analysis that could result in two or more different types of visualizations
Which of the following conclusions is BEST supported by the histogram chart?
More than half of all states are larger than 100,000 square miles
More than half of all states are smaller than 50,000 square miles
Some states are larger than 200,000 square miles
The most common size of states is between 50,000 and 100,000 square miles
A restaurant is interested in learning about the food preferences of people living nearby to the restaurant and intends to use survey data to help decide which new items to add to the menu. Which of the following is LEAST likely to be part of the process used to analyze the data?
Cleaning a data visualization to remove unwanted patterns
Iteratively creating visualizations to ask and answer new questions
Cleaning data to remove inconsistencies
Filtering the data to look at the responses from only certain groups
A town decides to publicize data it has collected about electricity usage around the city. The data is freely available for all to use and analyze in the hopes that it is possible to identify more efficient energy usage strategies.
Which of the following does this situation best demonstrate?
Citizen science
Crowdfunding
Open data
Machine Learning
A series of algorithms that endeavors to recognize underlying relationships in a set of data through a process that mimics the way the human brain operates.
Data Training
Neural Networks
Algorithmic Modeling
Citizen Science
Which of the following works best when you want to visualize one column with few values?
Histograms
Scatter Plot

A team of researchers wants to create a program to analyze the amount of pollution reported in roughly 3,000 counties across the United States. The program is intended to combine county data sets and then process the data. Which of the following is most likely to be a challenge in creating the program?
A computer program cannot combine data from different files.
Different counties may organize data in different ways.
The number of counties is too large for the program to process.
The total number of rows of data is too large for the program to process.
A camera mounted on the dashboard of a car captures an image of the view from the driver’s seat every second. Each image is stored as data. Along with each image, the camera also captures and stores the car’s speed, the date and time, and the car’s GPS location as metadata. Which of the following can best be determined using only the data and none of the metadata?
The average number of hours per day that the car is in use
The car’s average speed on a particular day
The distance the car traveled on a particular day
The number of bicycles the car passed on a particular day
Which of the following applications is most likely to benefit from the use of crowdsourcing?
An application that allows users to convert measurement units (e.g., inches to centimeters, ounces to liters)
An application that allows users to purchase tickets for a local museum
An application that allows users to compress the pictures on their devices to optimize storage space
An application that allows users to view descriptions and photographs of local landmarks
A mobile application is used to display local traffic conditions. Which of the following features of the application best exemplifies the use of crowdsourcing?
Users can save an address to be used at a later time.
Users can turn on alerts to be notified about traffic accidents.
Users can submit updates on local traffic conditions in real time.
Users can use the application to avoid heavily congested areas.
Research where some of the data collection is done by members of the public using own computing devices which leads to solving scientific problems
