CSP Unit 5 Data Analysis and Graphs Review for Students

What is metadata?

Metadata is data that provides information about other data. An example of metadata is the author, date created, and file size of a document.

What is a Bar Chart?

A Bar Chart is a graph of data using bars of different heights or lengths to compare different categories.

What is a Histogram?

A Histogram is a graph showing the frequency of data points within specified ranges (bins).

What is a Cross Tab?

A Cross Tab is a method to quantitatively analyze the relationship between multiple variables by displaying data in a matrix format. ( Like a google sheets chart)

What is a Scatter Plot?

A Scatter Plot is a type of graph that uses dots to represent the values obtained for two different variables, showing how much one variable is affected by another.

What is a benefit of using a Bar Chart?

A benefit of using a Bar Chart is that it clearly compares different categories that makes it easier to see differences in values

What is a disadvantage of using a Bar Chart?

A disadvantage of using a Bar Chart is that it can become cluttered and hard to read if there are too many categories.

What is a benefit of using a Histogram?

A benefit of using a Histogram is that it effectively shows the distribution of data and can highlight patterns such as skewness.

What is a disadvantage of using a Histogram?

A disadvantage of using a Histogram is that it may obscure individual data points and does not show exact values.

What is a benefit of using a Cross Tab?

A benefit of using a Cross Tab is that it allows for easy comparison of multiple variables and their interactions.

What is a disadvantage of using a Cross Tab?

A disadvantage of using a Cross Tab is that it can become complex and difficult to interpret with too many variables.

What is a benefit of using a Scatter Plot?

A benefit of using a Scatter Plot is that it visually represents the correlation between two variables, helping to identify trends.

What is a disadvantage of using a Scatter Plot?

A disadvantage of using a Scatter Plot is that it may not effectively convey information if there are too many data points overlapping.

What does crowdsourcing mean?

Crowdsourcing is the practice of obtaining information, ideas, or services from a large group of people, typically via the internet.

What is citizen science?

Citizen science is a collaborative effort where volunteers contribute to scientific research, often by collecting data or making observations.

What is meant by the term 'Big Data'?

Big Data refers to extremely large data sets that can be analyzed computationally to reveal patterns, trends, and associations.

When would parallel systems be used?

Parallel systems are used when processing large data sets simultaneously to improve efficiency and speed of data analysis.

What is an example of Open Data?

An example of Open Data is government datasets available to the public, such as census data or environmental statistics.

What are the 4 steps in the data analysis process?

The 4 steps in the data analysis process are: 1) Data Collection, 2) Data Cleaning, 3) Data Analysis, and 4) Data Interpretation.

How can we make sure a survey or data will not have a bias?

To ensure a survey or data does not have bias, use random sampling methods and ensure diverse representation of the population.

Give an example of data that contained bias.

An example of biased data is a survey conducted only among a specific demographic group, such as only surveying students from one school.
