Data Literacy TrainingClimate Change and Budget Data

Anjesh Tuladhar

What is data literacy?

• Ability to read, use and communicate data as information

• Think critically about data– Understanding how to work with

large datasets, how they are produced, how to connect various datasets, how to interpret them

What is data?

• Webster meaning: “facts or information used usually to calculate, analyse, or plan

something”• Anything is data – text, image,

numbers, …• For computer to understand, data

needs to be in structured and machine-readable form

Why data literacy?

• Slowly but steadily data are forcing their way into every nook and cranny of the industry, company and job

Making sense with data

1. Prepare

• Ask questions• Collect data• Organise data• Cleanse data

2. Analyse

• Answer questions• Answer with

charts/summaries/filters• Identify patterns/relationships

3. Apply

• Use results to communicate answers

• Convince answers• Make decisions• Share visualisations

Just numbers

Climate Change and Budget Data• We will be using these data for

the hands-on practice

1. Prepare

• Ask questions• Collect data• Organise data• Cleanse data

Prepare: Questions

• Is climate change priority area for Nepal?– How much contribution does climate

related projects have in the total budget?– How much contribution each ministry has

in the climate projects?–Which ministry has the highest

contribution in climate change?

• A look at the specific projects

Prepare: Data collection

• Where’s the data on Climate Change and Budget?– Budget: redbook (mof.gov.np)– Climate change project: NPC report

• PDF?– Data extraction from PDF

http://goo.gl/oCzfaW

Data Extraction Tools

• CSV (most used open format)• Html (in websites)–many programming tools, google chrome

scraper

• Pdf – very difficult– Pdf2text, Tabula

Tabula

• Tabula is a tool for liberating data tables trapped inside PDF files.

• Tabula requires java and you have to run the software

http://tabula.nerdpower.org/

Tabula

• Upload the file• Highlight the table• Download the data in csv format• Challenges– Data not always in the correct

format– Need cleaning/organising

Downloaded from Tabula

Prepare: Organise data

• Data not in usable form• data not being able to use

formula if in such format• Use tools like excel, google refine

to organize data– Add columns, remove columns, edit

columns, add new fields

Prepare: Clean data

• Data might still have issues• The PDF data have comma and

they are not numbers– They are text and can’t be summed

up, – Search and replace comma

After organising and cleaning

Analyse

• Answer questions• Answer with

chart/summaries/filter• Identify patterns/relationships

http://goo.gl/4ZuoiC

Analyse: Answer

• How much contribution does climate related projects have in the total budget?– Add climate related projects budget– Simple addition formula

Analyse: Answer

• How much contribution each ministry make to the climate change?– Not so simple answer– Try for 5 minutes– Create suitable chart

Analyse: Answer

• How much contribution each ministry has in the climate change?– Use of Pivot table– 10 seconds– Create suitable chart

Analyse: Answer

• Which ministry has the highest contribution in terms of their budget share?– Can you do it now?– HINT: You will need to get data from

two sources and work in a third sheet

– Create suitable chart

Apply

• Using results to communicate answers

• Make decisions• Visualisations• Create stories from the data

Apply: Visualisations

• Putting patterns on the screen• Identify the outliers• Allows access to large amount of

data• Makes data relevant

Visualisations: Datawrapper

• Created by journalists for journalists

• Go to http://datawrapper.de • Create account and paste

relevant data for sharing

Next: Iterate, Iterate, Iterate…
