You are working with a normally distributed data set. How would the standard deviation help you understand the data?
- It can tell you how spread out the data is around the mean
- It can tell you the range of the data
- It can tell you the skewness of the data
- It can tell you where the outliers are
For a normally distributed dataset, the "Standard Deviation" tells you "How spread out the data is around the mean". In a normal distribution, about 68% of values are within 1 standard deviation from the mean, 95% within 2 standard deviations, and 99.7% within 3 standard deviations.
How can a Uniform Distribution be transformed into a Normal Distribution?
- By adding a constant to each value
- By applying the Central Limit Theorem
- By squaring each value
- It can't be transformed
A Uniform Distribution can be approximated to a Normal Distribution by the application of the Central Limit Theorem, which states that the sum of a large number of independent and identically distributed variables, irrespective of their shape, tends towards a Normal Distribution.
A wildlife study records the number of different bird species seen during each observation period. How would you classify this data type?
- Continuous data
- Discrete data
- Nominal data
- Ordinal data
The number of different bird species seen during each observation period is a count and therefore classified as discrete data.
Suppose you're given a task to find the outliers in the multivariate dataset. Which plot will be helpful in this context and why?
- Bar Plot
- Box Plot
- Histogram
- Scatter Plot
A scatter plot would be helpful in finding outliers in a multivariate dataset. By plotting different variable combinations, you can identify points that fall far from the general distribution, which could indicate potential outliers.
Which measure of central tendency will be most affected in a scenario where the dataset has extreme values?
- Mean
- Median
- Mode
- nan
The "Mean" or average will be most affected in a scenario where the dataset has extreme values. Since the mean is calculated by taking into account all values in the dataset, outliers or extreme values can cause significant shifts in the mean, making it less representative of the dataset's central tendency.
_____ imputation is a basic method of handling missing data by replacing missing values with the most frequent category (for categorical variables).
- Listwise
- Mean
- Median
- Mode
'Mode' imputation is a basic method of handling missing data by replacing missing values with the most frequent category (for categorical variables). It is easy to implement but might introduce bias by overrepresenting the most frequent category.
Component _______ can be customized in child components to provide different functionality.
- Code
- Policies
- Structure
- Styles
Component structure can be customized in child components to provide different functionality. This allows developers to extend and override specific aspects of the parent component's structure while maintaining inheritance.
Scenario: A project requires the integration of a third-party JavaScript library into an AEM Touch UI Dialog. What considerations should be taken into account for this task?
- Ensure compatibility of the library with AEM's Touch UI
- Implement proper error handling for the library integration
- Include the library in the client library folder of the AEM project
- Test the library's functionality thoroughly before deployment
When integrating a third-party JavaScript library into an AEM Touch UI Dialog, it's crucial to include the library in the client library folder of the AEM project to ensure it's loaded properly.
What technology is the foundation of the AEM Content Repository (CRX)?
- Extensible Markup Language (XML)
- HyperText Transfer Protocol (HTTP)
- Java Content Repository (JCR)
- Structured Query Language (SQL)
The AEM Content Repository (CRX) is built on the Java Content Repository (JCR) technology, providing a robust and scalable foundation for storing and managing content.
Scenario: An organization wants to implement AEM for its global web presence. Which AEM feature would be most useful for managing content in multiple languages and regions?
- Cross-Cultural Syndication
- Global Content Repository
- Multilingual Content Management
- Translation Integration
For managing content in multiple languages and regions, the Multilingual Content Management feature in AEM is crucial. It enables efficient handling of diverse language and regional requirements.
The _______ between AEM components and templates allows for efficient content management.
- Collaboration
- Integration
- Linkage
- Relationship
The relationship between AEM components and templates is crucial, enabling efficient content management and dynamic page creation.
What is the purpose of AEM Content Services when dealing with Content Fragments?
- Create marketing campaigns
- Design graphical interfaces
- Expose content as RESTful APIs
- Monitor content engagement
AEM Content Services enable the exposure of content fragments as RESTful APIs, facilitating seamless integration with other systems and applications.
