Lecture Objectives

Students will be able to:Summarizing data in different waysRight graph and table for the right data and audience

Self-explanatory and attractive graphics and effects

The Way You Present Yourself Is a Key for Success

Do you present yourself like this? ->

Do you think you wouldtaken seriously?

3

So, if you know that you would not be taken seriously if you presented yourself like this, then . . .

Would most people be able to get the message from this data ?

4

No, it is too busy and it is

difficult to interpret.

The way you present your

data can greatly affect how

usable the data will be.

What about this

Can anyone tell me what some problems may be with this chart?

5

- No title

- No axis labels

(You should never put a dark color on a dark background.)

- The colors are difficult

to read. The green color is too bright.

IS This Better!!

In Tanzania,

P. falciparum

malaria, which is spread by the anopheles mosquito, is the leading cause of death among children under the age of five years. Young children have increased susceptibility to symptomatic malaria as they have not yet acquired immunity to the malaria parasite.

Pregnant women are also especially vulnerable because their immunity to the parasite is suppressed during pregnancy and the parasite often sequesters itself in the placenta – leading to both maternal morbidity due to anemia and low birth weight deliveries.

Mosquitoes need standing water to breed. Therefore, there are more mosquitoes in the environment (and thus higher malaria transmission) during the rainy season than during the dry season. There are two rainy seasons in Tanzania: from October through January and from March through May (Figure 2).

Malaria control efforts in Tanzania focus on the following three interventions to prevent malaria among women and children under five years of age including:

Bednets

:

Used correctly,

bednets

offer protection from mosquito bites and thereby reduce the transmission of malaria. While all

bednets

can protect the people sleeping under them, insecticide-treated nets (ITN) are especially effective because they both block the mosquito bite and kill any mosquitoes that land on the net. Pilot studies promoting ITNs have shown increased child survival and reduced anemia among children under five years of age, as well as reduced maternal morbidity and low birth weight deliveries.

Intermittent Preventive Treatment in Pregnancy :

Intermittent preventive treatment in pregnancy (

IPTp

) reduces placental malaria and anemia in pregnant women as well as the incidence of low birth weight deliveries. The regimen for

IPTp

recommended by the World Health Organization (WHO) is two to three doses of

sulfadoxine

-pyrimethamine (SP) given to pregnant women after quickening (the first fetal movements felt by the mother) in the second and third trimesters during routine antenatal care visits. As resistance to SP is growing in much of sub-Saharan Africa, researchers are investigating the efficacy of this drug for

IPTp

and exploring the safety of other more effective medications for this purpose.

Prompt and Effective Treatment :

To reduce morbidity and mortality from malaria, young children should be treated as soon as symptoms (usually fever) appear. Moreover, it is important that they receive the correct medication. In much of sub-Saharan Africa, the malaria parasite has developed resistance to older medications such as chloroquine, amodiaquine and

sulfadoxine

-pyrimethamine. Consequently, Tanzania has changed its treatment guidelines to recommend treatment with artemisinin-based combination therapies (ACTs).

Effective Presentation

In your presentation it is important to ensure:Consistency

Font, Colors, Punctuation, Terminology, Line/ Paragraph SpacingAn appropriate amount of information

Less is more Appropriate content and format for audience Scientific community, Journalist, Politicians

9

- Limit to six lines with no more than six words per line.

Balance text with graphics.

Make sure that there are not too many slides.

Self explanatory Graphics

Ensure graphic has a title or headingLabel the x- and y-axes of your graphic

Include value labels such as a percentage sign, and legend.Indicate source of data with date (Cite the source of your data)

Provide number of observations (n=xx) as a reference pointAdd footnote if more information is needed

Data Presentation Tips

All text should be readableUse

sans serif fontsGill Sans, Arial … (sans serif)

Times New Roman (serif)Use graphs or charts, not tables

Keep slides simple

Limit animations and special effects

Use high contrast text and backgrounds

11

Avoid having text in less than 25 point

Use no more than 2 typefaces per presentation.

Nothing in your slides should be superfluous (no extra doodads for decoration).

A light background with dark text (such as this one)

Data Presentation

The two main ways of summarizing data are by using:1- TablesSimplest way to summarize dataData is presented as absolute numbers or percentages

2- Charts and graphsVisual representation of dataUsually data is presented using percentages.

12

Tables and graphs are used to:

- Convey a message.

- Stimulate thinking.

- Portray trends, relationships, and comparisons.

Informative graphs are simple and self-explanatory

.

Table

A table is the simplest way of summarizing a set of observations. A table has rows and columns containing data which can be in the form of absolute numbers or percentages, or both.

13

Tables can be good for side-by-side comparisons, but can lack visual impact when used on a slide in a presentation.

Summary

Make sure that you present your data in a consistent format

Use the right graph for the right data and the right audience

Label the components of your graphic (title, axis)

Indicate source of data and number of observations

Add footnote for more explanation
