In a significant paradigm shift, data analytics will allow auditors to:
stay engaged with clients beyond the audit
Data Analytics
the process of evaluating data with the purpose of drawing conclusions to address business questions.
As part of mastering the data, data analysts perform data __________ to provide a sense of reliability of the data
validation and completeness
Classification
A data approach that attempts to assign each unit in a population into a few categories potentially to help with predictions

Develop an analytics mindset Data scrubbing and data preparation Data quality Descriptive data analysis Data analysis through data manipulation Define and address problems through statistical data analysis Data visualization and data reporting
Big Data
data-sets that are too large and complex for businesses' existing systems to handle utilizing their traditional capabilities to capture, store, manage, and analyze these datasets.
Which approach to Data Analytics attempts to predict relationship between two data items?
link prediction
Accountants must know how to:

Profiling
a data approach that attempts to characterize the "typical" behavior of an individual, group, or population by generating summary statistics about the data (mean, standard deviation)
regression
a data approach that attempts to estimate or predict , for each unit, the numerical value of some variable using some type of statistical model
similarity matching
a data approach that attempts to identify similar individuals based on data known about them
Link Prediction
a data approach that attempts to predict a relationship between two data items
Data reduction
a data approach that attempts to reduce the amount of information that needs to be considered to focus on the most critical items (highest cost, highest impact)
predictor (independent/explanatory) variable
a variable that predicts or explains another variable
response (dependent) variable
a variable that responds to or is dependent of another
