Refer to the exhibit.An app that will track experiments for rodents (e.g., rats and mice) that navigate mazes (labyrinths) is being developed. Individual rodents are catalogued in the Rodent table, while the Mazes table has metadata for the mazes. The MazeEscapes table holds a record of each attempt at a maze by a rodent. A business analyst needs to build a KPI that will allow users to see how many rodents have made at least one attempt at any maze.How should the analyst construct the KPI?
Answer(s): A
In this case, we need to count how many unique rodents have made at least one attempt at any maze. Since the relationship between the Rodent table and the MazeEscapes table is a one-to-many relationship (each rodent may attempt several mazes), the best approach is to base the calculation on the MazeEscapes table, as it holds the actual records of rodent attempts.By creating a new field RodentID_Counter in the MazeEscapes table, the analyst ensures that each rodent's attempt is captured. Using the Count (Distinct RodentID_Counter) as the KPI expression then accurately counts each unique rodent that has made at least one attempt, without counting multiple attempts by the same rodent.Key Concepts:Distinct Count: The distinct count ensures that rodents who have made multiple maze attempts are only counted once.MazeEscapes Table: This table holds the records of each attempt, making it the correct source for this KPI.Why the Other Options Are Less Suitable:B . Sum (RodentID_Counter) in the Rodent table: This would incorrectly sum the number of rodents rather than counting unique attempts, leading to inaccurate results.C . Sum (RodentID_Counter) in the MazeEscapes table: Summing the counter would not account for the distinct rodents, leading to incorrect counting.D . RodentID_Counter in the Rodent table: This would not correctly reflect the rodents that have made an attempt, as not every rodent in the Rodent table may have attempted a maze.References for Qlik Sense Business Analyst:Distinct Count in KPI: It is best practice to use Count(Distinct ...) when working with KPIs that require unique counts, such as counting distinct rodents in this scenario. Thus, A is the verified answer because it ensures that each rodent is counted once, based on their attempts in the MazeEscapes table.
A business analyst needs to create a visualization that compares two measures over time using a continuous scale that includes a range. The measures will be Profit and Revenue.Which visualization should the business analyst use?
A line chart is the most appropriate visualization for comparing two continuous measures (Profit and Revenue) over time. Line charts are designed to show trends and patterns over a continuous scale (such as time), making it ideal for this scenario where we need to observe how both Profit and Revenue vary across a period.Key Concepts:Continuous Scale: Line charts are specifically suited for continuous data like time, making them the preferred choice when tracking changes over time for multiple measures. Dual Measure Comparison: A line chart allows you to plot two measures on the same axis, making it easy to compare their trends over the same period.Why the Other Options Are Less Suitable:B . Bullet chart: A bullet chart is used to compare a single measure against a target, not for tracking two measures over time.C . Bar chart: Bar charts are better suited for comparing categorical data, not continuous measures over time.D . Scatter plot: Scatter plots are used to compare relationships between two measures but are not suited for continuous time-based comparisons.References for Qlik Sense Business Analyst:Line Charts for Time Series Data: Line charts are the recommended visualization for comparing multiple measures over time in Qlik Sense, especially when working with continuous data like Profit and Revenue.Thus, the line chart is the best choice for this scenario, making A the correct answer.
The VP of Sales asks a business analyst to include a KPI object on the sales dashboard that shows total sales value for the year 2022, regardless of selections. Existing fields in the data model include Sales and Year.How should the business analyst write the measure for the KPI object?
Answer(s): C
In this scenario, the VP of Sales wants to see the total sales for the year 2022 regardless of selections. This requirement is best handled using Set Analysis in Qlik Sense. The key to achieving this is using the set identifier 1, which ignores the user's selections and ensures the calculation is based on the entire dataset. The expression Sum( { 1 < year = { '2022' } > } Sales) calculates the sum of sales for the year 2022, irrespective of any other selections made in the app.Key Concepts:Set Identifier 1: This identifier ensures that the calculation is performed on the entire dataset, ignoring any selections or filters applied by the user. Year Filtering: The expression < year = { '2022' } > ensures that only sales from the year 2022 are included in the calculation.Why the Other Options Are Less Suitable:A . Sum( { < year = '2022' > } Sales): This is incorrectly formatted, and the pipe (|) symbol should not be used in this context.B . Sum( { $ < year = { '2022' } > } Sales): The $ set identifier respects the current selections, which is not what is needed in this case, as the VP wants the value to be shown regardless of selections. D . Sum( 1 { < year = { '2022' } > } Sales): The placement of 1 is incorrect in this expression.References for Qlik Sense Business Analyst:Set Analysis: Qlik Sense's Set Analysis allows analysts to control what data is used in a calculation, regardless of user selections. The set identifier 1 ensures that selections are ignored, which is essential for showing fixed data such as total sales for a specific year. Thus, the correct expression to show the total sales for 2022, regardless of user selections, is C.
A banking organization needs a dashboard that shows the following:· A KPI indicator for current year (CY) versus last year (LY) revenue · A scatter plot that shows the cost versus revenue of product categories · A treemap that shows average customer satisfaction rating based on regions · A table that shows CY cost by record number, financial instrument, and bank In addition to the customer satisfaction rating, which fields should be used to create the required measures?
The banking dashboard requires several KPIs and visualizations based on current year (CY) and last year (LY) revenue, as well as cost and customer satisfaction. To build the required measures, the fields CY Revenue, LY Revenue, and CY Cost are necessary because they provide the comparison between the current and previous year, as well as cost-related data for the specific calculations.Key Concepts:KPI for CY vs LY Revenue: This requires both CY Revenue and LY Revenue fields. Scatter Plot for Cost vs Revenue: This comparison requires both CY Revenue and CY Cost to create the necessary relationship in the scatter plot.Treemap for Customer Satisfaction: In addition to the customer satisfaction rating, the field CY Revenue would likely be used for additional insights by region. Table with CY Cost: The table requires CY Cost data along with other relevant fields like record number, financial instrument, and bank.Why the Other Options Are Less Suitable:B . CY Revenue, LY Revenue, Cost: While this covers the revenue fields, it does not specifically include CY Cost, which is needed for the table and scatter plot. C . Revenue and Cost: This option is too general and does not distinguish between current year and last year revenue, which is essential for the KPI.D . Revenue and CY Cost: This does not include LY Revenue, which is required for the KPI.References for Qlik Sense Business Analyst:Comparison Measures in Qlik Sense: In Qlik Sense, comparisons across time periods like CY and LY require specific fields to calculate accurate insights, and it's essential to ensure the appropriate fields are included for each visualization.Thus, A provides the correct set of fields for the required dashboard, making it the verified answer.
A data analyst is working on a new Qlik Sense application and realizes that some of the required data sources have already been used in previous applications. To streamline the data loading process and maintain consistency, the analyst decides to leverage existing data connections. What actions should the analyst take to utilize the pre-existing data connections in Qlik Sense?
Answer(s): B
In Qlik Sense, data connections are reusable objects that allow multiple apps to connect to the same data sources. To leverage existing connections, the business analyst should go to the Data Load Editor and select the desired connection from the list of available connections. This ensures that the analyst uses the same data sources, promoting consistency across apps.Key Concepts:Data Connections: Qlik Sense allows users to create and manage connections to external data sources. These connections can be reused across multiple applications. Data Load Editor: This is where existing data connections can be accessed and used in new applications, streamlining the data loading process.Why the Other Options Are Less Suitable:A . Copy the script from the old application and paste it into the new application's script editor:While this could work, it's not the most efficient method, as it doesn't reuse the existing data connection object, and it's prone to errors.C . Export the data connection from the old application and import it into the new one: Qlik Sense doesn't require exporting and importing data connections since they are already available globally for reuse across apps.D . Use a Qlik Sense extension to search and replicate data connections: This is unnecessary because Qlik Sense already allows direct access to existing data connections through the Data Load Editor.References for Qlik Sense Business Analyst:Reusing Data Connections: One of the key features of Qlik Sense is its ability to reuse data connections across apps, which helps maintain consistency and reduces the need for redundant setups.Thus, the correct approach is to access the Data Load Editor and select the pre-existing data connection, making B the verified answer.
