Exam 1 Flashcards
What is the approach of accounting data analytics?
Data analytics can assist in uncovering unseen patterns and knowledge in vast quantities of data and software. Accounting data analytics is a subset of data analytics focusing on: transactions, examines data for fraud and errors, facilitates the audit function
Fraud
The material, purposeful, misrepresentation of information characteristics, in order to gain assets, leverage or anything of value from another
Occupational Fraud
Fraud in the workplace
Abuse
Inappropriate workplace behavior or events to which the definition of fraud does not fit in
Anomalies
Unusual occurrences or data values
Broad Categories of fraud types
- Misappropriation of assets
- Financial statement fraud
3 Corruption Fraud
- What are the approaches by which organizations measure and address risk?
- Avoiding
- Bearing
- Mitigating
- Share
Traditional Fraud Detection approach
=> Do not directly observe occupational fraud
=> Observe indicators, symptoms or red flags of occupational fraud
=> These observations are referred to as anomalies
=> Investigate the anomalies to see if fraud actually occurred
Standard method is to identify a group of anomalies, examine a few transaction in the group to clear the entire group
Significant number of false positives occur among these anomalies
Due to the number of false positives, often do not get the attention these deserve
Accounting Data Analytics approach
=> Use computers and specialized software to examine each transaction
=> Screen all the transactions to identify anomalies
Using specialized algorithms
=> Investigate the anomalies for fraud and errors
Can examine all or most of the anomalies
Describe the Data Analysis Cycle
Three stages of the data analysis cycle
- Evaluation and analysis
- Software and technology
- Audit and investigation
Types of Data
Categorical data
Characteristics or qualities of the data
Can use pivot tables to examine two-way categorization of the data
Quantitative Data
Numeric data
Numbers, values, counts
Types of numeric data
Cardinal data: numeric data with a natural zero
Score data: numeric data without a natural zero
Ordinal data: ranks, categories
May not perform arithmetic operations
Concepts underlying inferential statistics
=>The population is too large or costly to enumerate
=>Draw a sample that represents the population
Representation is the key
=>Calculate statistics of interest in the sample
Infer these to values to the corresponding population statistic
=>With data analytics the entire population may be examined
Search for anomalies
Inspect the anomalies (like a sample from the population)
Measures of central tendency
Mean
Median
Mode
Measures of Dispersion
=>Range =>Deviations from the mean =>Variance =>Standard Deviation =>Standard Deviation of a sample and a population
