Data Analysis Process and Engineering Quiz

Data Requirement Gathering = Decide what to analyze and how to measure it Data Collection = Collect your data based on requirements Data Cleaning = Data should be cleaned and error free Data Interpretation = Express or communicate your data analysis

Quantitative Data Analysis Methods = Quantitative data is defined as the value of data in the form of counts or numbers Qualitative Data Analysis Methods = Analysis of non-numeric data for patterns, themes, and meanings Counter = Count equated with entities Measurement of physical objects = Calculating measurement of any physical thing

Insights from unstructured information = Data analysis involves sorting through massive amount of unstructured information and deriving key insights from it Use of charts and graphs = Data Visualization often appears in the form of charts and graphs Value in decision-making = The insights derived from data analysis are enormously valuable for decision-making at companies of all sizes Data modeling and transformation = Data analysis is a process of inspecting, cleansing, transforming and modeling data with the goal of discovering useful information

<p>Nominal Scale = Numbers serve as tags or labels only, to identify or classify an object Ordinal Scale = Reports the ranking and ordering of the data without establishing the degree of variation between them Interval Scale = Quantitative measurement scale where there is order, the difference between the variables is meaningful and equal, and the presence of zero is arbitrary Ratio Scale = Similar to interval scale but has a true zero point</p> Signup and view all the answers
