• sweet
• Male or female

• Quantitative data is about numbers. For example, since 2015 CSY volunteers have collectively taught over 85,000 students at 61 different schools
• Qualitative data describes characteristics…. For example stories

Data type

​

• Over 850 Alumni St Jude's alumni

​

St Jude's data

​

…to make important decision data is used to change policies…

example …

• 70% of children aged 14–17 years not enrolled in secondary education

​

• Transform data into “information” that is used for decision making

​

• Changed education policy in Tanzania 2015…

​

• More students in school now….

​

​

Is Data powerful and insightful?

Data comes from a random process……

​

Part of it we understand and part of it we don’t understand

​

Such as physical process is like tossing a die, flipping a coins

​

The goal is to make predictions.. accurate guess

​

To understand randomness we need… Probability..?

​

​

​

Where data come from?

Rolling 1 die……

​

Edna gets Tsh 100 if # of dots <= 3

​

Simon gets Tsh 200 if # of dots <= 2

​

Who do you want to be ?

​

Edna or Simon? Why?

​

​

Example?

Do you represent yourself like this?

• Why would you not present yourself like this?

​

• Do you think this man is taken seriously?

​

• What do you think would happen if he tried to speak to someone in the Ministry of Health about some information related to a healthy eating program?

​

• Data collection need a thoughtful process to avoid confusions and misinterpation ..

​

• How do you do it?......

​

​

​

​

​

​

​

Knowing what to measure and how to measure……..

• Have a clear, preferably written statement of your objectives. For example, performance

​

• Before you initiate data collection, you must have a firm idea of what you will measure. For example, test scores

​

• Always think of data availability and accessibility

​

• Then think of the tools for collecting data…..

​

​

​

​

​

​

Getting the basics right…

1. Primary source examples……

• Observation
• Questionnaires
• Focus group discussion

​

2. Secondary sources examples….

• Books
• Internet

​

​

What are the tools for collecting data?

​

• Samples should be as representative as possible of the total population to reduce sampling error and sampling bias

​

• Population: Is an entire collection of measurements of a variable under study i.e. it encompasses all the observations about which we wish to draw conclusions.

​

• Sample; Is a subset of the population? It is a relatively small number of observations from the population being investigated

​

• Variable: A property of an individual population unit (e.g. major, height, weight)

​

​

​

​

​

Population and sampling

​

​

​

​

​

Population and sampling ?

​

• Let’s do an experiment
• Take 1 Random test score from the pile of 16,000 tests
• Write down the value
• Put the test back
• Do these three steps again
• And again
• 8,000 times
• This is like a random sample of 8,000 (with replacement)

​

​

​

Population and sampling distribution ?

​

​

​

​

Population and sampling distribution ?

​

• Detecting impact ??? Example ……….
• Baseline test score of the program

​

​

What are we using this for ?

​

​

End line test score ?

​

​

Impact ?

​

​

• To know if we meet targets
• To improve decision making
• For corrective actions

​

How do we do that…by measuring;

1. before situation i.e. baseline
2. after situation i.e end line survey

​

Through….what tool?

​

Filling questionnaires ..

​

How to fill questionnaires???
