Tableau Definitions Flashcards
Qualitative Field
DIMESION Describes characters in data tells you who, what, when it is used to slice qualitative data.
Quantitative data
MEASURES numeric data provides the measurement for qualitative data can be used in calculations
Dimensions
Qualitative Data, is a part or way of considering something. qulatitive, descriptive and qualatitive. Cn be number talks about the qualities of something. it is a blue pill
Measures
Quantitative Data, can be an amount or degree. it is where a calculation can be made ( sum, average, add, subtract) Green Pills (Axis) 200 500, 1, 34,5 it is quantitive, numeric typically aggregated.
When we add more XXX we get a better picture of the dataset and break it down into smaller measures.
Measures, Qualitative
Adding a xx helps you focus on a specific subset of the data
filter
Detailed data
granular data
granular data
Detailed data
Data aggregation
Combined data
the more the set is broken down
granularity- more data points
Putting segment into color
colors segment
If we add to size
adds size data
Continuous data
means data value and contain numbers in a range
continuous fields
are mostly measures
Discrete Data
have distinct separate values
Dimensions and Measures
what the data is, what the data represents. it is the meaning of that data.
What are dimensions
Describes or catergorizs data
tells you what wen or who
Slices the quantities data
Quantative field measures
Numerical data
Provides the measurement for a qualatitive category
Can be used in calculations
Dimensions and measures are the building block of Tableau charts
When tableau connects to a data set it assigned the fields to either dimensions or measures
The qualitative fields that describe categories of data are in the top part of the pane under dimensioms
The qualative fields that measure categories of data are in the bottom part of the pane under measures
In the top or columns it creates a long bar and an axis showing a range of values
Thequantative fielding green tells us how many
Weneedto bring in the qualitative fields in to better understand our data. If we add the dimension animal category we can see birds make up most of the wildfire strikes the single bar breaks into four one for each category. Dimension fields display in blue when brought into the sheet
