Question:
Imagine you are a Scrum Master. There are 10 professionals (developers and QAs) and the Product Owner. How to distribute people between development teams? Choose all applicable variants:
3 teams of 4, 3 and 3 people (each team is cross-functional)
2 teams of 6 and 4 people (the professionals after a short meeting decided this is the best variant)
2 teams of 6 and 4 people (because it is good to have all the QAs in a separate team)
1 team of 10 people (because there is no reason to divide)Answer : : A & B
Optimal Development Team size is small enough to remain nimble and large enough to complete significant work within a Sprint. Fewer than three Development Team members decrease interaction and results in smaller productivity gains. Having more than nine members requires too much coordination. The Product Owner and Scrum Master roles are not included in this count unless they are also executing the work of the Sprint Backlog.

Data Visualization using python libraries | matplotlib I Seaborn | plotl...

Visualization is any technique for creating images, diagrams, or animations to communicate a message.
Types of Data Visualizations :
Explanatory:
Exploratory:

Python Visualisation Libraries
• Matplotlib
o https://matplotlib.org/
• Pandas built-in plotting
• ggpy
o https://github.com/yhat/ggpy
• Altair
o https://altair-viz.github.io/
• Seaborn
o https://seaborn.pydata.org/
• Plotly

Visualization methods :
Distribution
It is commonly used at the initial stage of data exploration i.e. when we get started with understanding the variable. Variables are of two types: Continuous and Categorical. For continuous variable, we look at the center, spread, outlier. For categorical variable we look at frequency table.
Histogram : It is used for showing the distribution of continuous variables.
Box-Plot : It is used to display full range of variation from min to max and useful to identify outlier values.
Comparison
It is used to compare values across different categories.
Common charts to represent these information are Bar and Line chart.
Bar Chart : It is used to compare values across different categories
Line Chart : It is used to compare values over quantitative variable
Composition
It is used to show distribution of a variable across categories of another variable
Pie Chart : It can be created by passing the values representing each of the slices of the pie.
Relationship
It is widely used to understand the correlation between two or more continuous variables
Scatter Plot : It clearly shows the relationship between two variables
