**SOFTWARE**

### Microsoft Azure Machine Learning Studio

A drag-and-drop tool with a graphical user interface for building, testing and deploying predictive analytics solutions on your data.

### SAS Enterprise Miner

A solution for creating accurate predictive and descriptive data models using data mining and statistical techniques such as linear regression, clustering and classification (decision trees).

### Jupyter Notebooks

Jupyter Notebooks are used to explore datasets through an interactive browser-based environment in which you can add notes and run code to manipulate and visualise data. They support languages regularly used by data scientists such as R and Python.

**PROGRAMMING LANGUAGES**

### R

R is an open source programming language and software environment widely used for statistical analysis, testing and modelling.

### Python

Python is another programming language used for detailed statistical analysis, testing and modelling.

**VISUALISATIONS**

### Histogram

Similar in look to a horizontal bar graph except the bars are connected to each other, histograms are formed from grouped data to display frequencies or relative frequencies (percentages) for each class in a sample.

### Scattergrams

A method of displaying the correlation between two or more variables, including a line of best fit to demonstrate how far each observation deviates from the mean.

### Frequency polygon

Line chart plotted at the mid-point of each class, with the classes grouped e.g. into 0-10, 11-20, etc.

### Venn diagram

Presented as two or more circles overlapping each other to demonstrate relationships between variables.

Example: Animals with two legs and animals who can fly. Some would show in one group or the other and some would overlap into both groups.

### Tree diagram

Uses probability to demonstrate outcomes based on more than one input.

Example: The first branch could be Europe, the second branches splitting out Germany, France and Spain and then the third branches split out the various cities in those countries.

### Box plots

A one-dimensional graph based on the numerical data from the five-number summary.
