1Which type of data analytics is primarily concerned with answering the question, 'What is likely to happen in the future?'
A.Descriptive analytics
B.Diagnostic analytics
C.Predictive analytics
D.Prescriptive analytics
Explanation: Predictive analytics uses historical data, statistical algorithms, and machine learning techniques to identify the likelihood of future outcomes. Unlike descriptive or diagnostic analytics, which look backward, predictive analytics focuses on forecasting future trends and behaviors. Prescriptive analytics goes a step further by recommending specific actions to take based on those predictions.
2During which phase of the CRISP-DM (Cross-Industry Standard Process for Data Mining) cycle does an analyst define the project objectives from a business perspective?
A.Data Understanding
B.Business Understanding
C.Data Preparation
D.Evaluation
Explanation: The Business Understanding phase is the first step in the CRISP-DM methodology. It focuses on understanding the project objectives and requirements from a business standpoint, and then converting this knowledge into a data mining problem definition and a preliminary plan. Data Understanding and Preparation occur later in the cycle once objectives are established.
3An analyst wants to determine why sales dropped significantly in the last quarter. Which type of data analytics is best suited for this task?
A.Descriptive analytics
B.Diagnostic analytics
C.Predictive analytics
D.Prescriptive analytics
Explanation: Diagnostic analytics is used to investigate historical data to answer the question, 'Why did it happen?'. It involves techniques like drill-down, data discovery, data mining, and correlations to identify root causes of trends or anomalies. Descriptive analytics only states what happened, while predictive and prescriptive look forward.
4Which of the following describes qualitative (categorical) data?
A.The monthly revenue of a retail store in euros
B.The customer satisfaction rating categorized as Poor, Fair, Good, or Excellent
C.The temperature of a server room recorded in degrees Celsius
D.The number of website visits per hour
Explanation: Qualitative or categorical data represents characteristics or attributes that can be sorted into distinct groups or categories, such as satisfaction ratings (Poor, Fair, Good, Excellent). Monthly revenue, temperature, and website visits are quantitative (numerical) data because they represent measurable quantities that can be counted or ordered on a numerical scale.
5A market researcher selects 500 customers out of a total database of 100,000 to complete a survey about a new product. In statistics, what term describes the group of 100,000 customers?
A.Sample
B.Population
C.Cohort
D.Control group
Explanation: In statistics, the population is the entire group of individuals or items that you want to draw conclusions about. The 100,000 customers represent the entire population. The 500 customers selected to complete the survey represent a sample, which is a subset of the population used to estimate characteristics of the whole.
6Which statistical measure of variation is calculated as the difference between the maximum and minimum values in a dataset?
A.Variance
B.Standard deviation
C.Range
D.Interquartile range
Explanation: The range is the simplest measure of variation and is calculated by subtracting the lowest value (minimum) from the highest value (maximum) in a dataset. While easy to calculate, it is highly sensitive to outliers. Variance and standard deviation measure dispersion around the mean, and the interquartile range measures the spread of the middle 50% of the data.
7A dataset of test scores has a First Quartile (Q1) of 60 and a Third Quartile (Q3) of 85. What is the Interquartile Range (IQR) for this dataset?
A.12.5
B.25
C.145
D.72.5
Explanation: The Interquartile Range (IQR) is calculated as the difference between the Third Quartile (Q3) and the First Quartile (Q1). Using the formula IQR = Q3 - Q1, we get 85 - 60 = 25. The IQR measures the spread of the middle 50% of the dataset and is resistant to the influence of outliers.
8A company wants to analyze employee salaries. The salaries are heavily skewed to the right due to a few executives earning extremely high amounts. Which measure of central tendency would be most appropriate to represent the 'typical' employee salary?
A.Mean
B.Median
C.Mode
D.Standard Deviation
Explanation: The median is the middle value when the data points are arranged in order. It is resistant to the effects of extreme outliers (skewed data). In a right-skewed salary distribution, the mean is pulled upward by high executive salaries, making it unrepresentative of a typical employee. The median represents the point where 50% of employees earn more and 50% earn less.
9Under data protection regulations like GDPR, what is the term for processing personal data in such a way that it can no longer be attributed to a specific data subject without the use of additional information?
A.Anonymisation
B.Pseudonymisation
C.Encryption
D.Data Minimisation
Explanation: Pseudonymisation is the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately. It reduces the risks associated with data processing but the data is still considered personal data. Anonymisation, on the other hand, permanently destroys the link, making the data non-personal.
10Which of the following is defined as personal data under the General Data Protection Regulation (GDPR)?
A.An IP address associated with a user's internet connection
B.A company's total annual revenue figure
C.Aggregated customer satisfaction percentages from 10,000 users
D.The average monthly temperature of a city
Explanation: Under the GDPR, personal data is any information relating to an identified or identifiable natural person. Since an IP address can be linked back to an individual (with the help of an internet service provider), it is legally classified as personal data. Corporate revenue, aggregated survey data, and weather metrics do not relate to identifiable individuals.

About the ICDL Data Analytics Exam
