First Party Data - (correct Answer) - Data you collect yourself
Second Party Data - (correct Answer) - Data is collected directly by another group then sold
Third Party Data - (correct Answer) - Data sold by a provider that did not collect the data themselves
Data Collection Considerations - (correct Answer) - Select The Right Type of Data
Determine the Time Frame
Collect New Data
Use Existing Data
Data Formats - (correct Answer) - Primary Vs Secondary, Internal Vs. External, Continuous Vs. Discrete,
Qualitative Vs. Quantitative, Nominal Vs Ordinal, Structured Vs. Unstructured
Structured Data - (correct Answer) - Organized in a certain format such as rows and columns
Unstructured Data - (correct Answer) - Not Organized in any easy way to identify
Data Modeling - (correct Answer) - Process of creating diagrams that visually represents how data is
organized and structured. These visual representations are called data models
Three most common types of data modeling - (correct Answer) - Conceptual Data Modeling, Logical Data
Modeling, Physical Data Modeling
Data Type - (correct Answer) - A specific Kind of data attribute that tells what kind of value the data is
Data Type in a Spreadsheet - (correct Answer) - Can be a number, text/string, or a Boolean
Boolean Logic - (correct Answer) - Uses Multiple conditions such as: boolean operators (AND, OR, NOT)
Data transformation - (correct Answer) - Process of changing the data's format, structure, or values
Goals of Data Transformation - (correct Answer) - Organization, Compatibility, Migration, Merging,
Enhancement, or Comparison
Biased Data - (correct Answer) - Can systematically skew results in a certain direction making them
unreliable. As an analyst, think about bias and fairness from the moment you start collecting data to
time you present your conclusion.
Sampling Bias - (correct Answer) - When a sample is not representative of the population as a whole.
Unbiased sampling results in a sample that is representative of the population being measured.
Observer Bias - (correct Answer) - The tendency of different people to observe things differently
