it is possible to add a field to more than one hierarchy TRUE. blends are a LEFT join that happens AFTER the data has been aggregated to the appropriate level. when you change the value of a parameter on one page of the storyline, it also changes on all other pages of the storyline FALSE approximately what percent of work of a data scientist is data preparation 70% what is the best format of data for machines in tableau where each measure and dimension has its own column which of these tableau 9 features allows you to change the format of the data from where the years are in columns to when the years have their own columns pivot which of the following is NOT a new feature introduced in tableau 10 3 dimensional dashboards what does a highlighter allow you to accomplish subtly highlight different marks on your chart based on the categories of the selected field without interfering with the charts visual representation (marks shown, sizes, etc) is it possible to specify additional variables for clustering analysis (apart from the variables present in your chart) yes, you can specify additional variables AND you can remove unwanted variables from the clustering analysis without removing them from the chart are clusters a dimension or a measure dimension- because they represent a categorical split of your data does the introduction of cross database joins render blends completely useless no. which of the following statements about what can be used as pages in a storyline is TRUE both worksheets and dashboards can be used as pages in a storyline. to deliver a better customer experience making it tailored and relevant. what is the main visual element of a treemap called box what are customer segmentation dashboards used for understand how customers are segmented across different geographies. when you simply cannot do a join for any other reason what is the first thing you need to do after creating a dual axis chart synchronize the axis how is creating calculated fields in a blend different to creating normal calculated fields the data elements used have to be aggregated how do you set geographic roles right click the appropriate field and select the appropriate geographic role which of the following is NOT a quick table calculation in tableau stochastic oscillation which of these are types of allowable values for any parameter all. when your data comes from disparate data sources. the table is extended horizontally what happens when one of the tables has duplicate values in the join clause the matching row of the other table is replicated to accommodate the number of duplicates what can happen when you join on a single field when it is required to join on multiple fields rows will be duplicated without an actual reason, hyper inflation of measures, incorrect insights and business decisions data blending in tableau happens after aggregation is performed on the separate datasets false when would you use data blending and not data joining when your datasets have different levels of granularity. you can automatically generate action: filter through the dropdown of the selected worksheet in the dashboard true which of these is a good rough description of what happens when two tables are joined the rows of the second table are placed to the side of the rows of the first. action: highlight all the data is visualized first and then the action is applied after. When would you need to create hierarchies in tableau when there are hierarchies present in the dimensions and tableau needs to know about them for you to build your visualization which of the following are different ways you can select the worksheets to which you want to apply a filter all using this data source, selected worksheets, only this worksheet to add worksheets to a dashboard you can simply drag them onto the dashboard true what is the main conceptual difference between action: filter and action: highlight for a dashboard when you use action: filter you are removing data from analysis before it is illustrated on the visualization.
