Statistic is series of data. Those data is usually in number form, arranged in a table or diagram. Statistic data usually describes something and has something to do with something.
When you deliver a presentation, you are challenged to deliver something related to data or facts so that the audiences get the point that what you deliver is something useful and real.
One of many data that affects the success of a presentation is statistic data. With those data, your presentation material will be more understandable to the audiences.
For instance, you are presenting a material about the danger of smoking to human health. In that presentation, you deliver the facts about substances inside a cigarette that can destroy health. These facts will be strengthened with statistic data. It could be the result about the research on the health damage caused by smoking, the increasing of the patients due to smoking and the relation between the amounts of cigarettes consumed daily to the heart health condition. All those data must be researched by statistics.
Besides for strengthening data and facts delivered in a presentation, statistic also has several important functions that are important for the success of your presentation.
1. Giving clearer description to the audiences
Imagine you are delivering a presentation about the importance of keeping the continuity of the forest. In that presentation, you say that 2 million hectare of forest in Indonesia is gone due to illegal logging.
When you say “2 million hectare”, the audiences will think that that is a large amount. But, only few people are able to imagine that 2 million hectare forest.
But, if you add another explanation like elaborating that ‘2 million hectare is equal to 10 thousand times of a soccer field’, almost all of the audiences are able to imagine how vast is the damage of the forest due to illegal logging. It could happen because the audiences are familiar with soccer field than a forest, especially if they live in the metropolitan city.
We got the fact from statistic data. It is impossible for you to measure the damaged forest all by yourself manually because it will be very difficult to do. But, statistics enables you to get data you need easily.
2. Giving easier explanation to the audiences
Imagine you are delivering a presentation about the benefits of strawberries for human health.
In order to be able to describe the benefits contained in strawberries, you must give the information about nutrition contained in strawberries. In that presentation, it is impossible to make a research like researches do in laboratory to give information about vitamin C consisted in a strawberry. You just need to give the existing data. For example you describe that a strawberry contains several grams of vitamin C. with that amount, people need several strawberries to keep healthy. Those data need statistic measurement.
If you want to compare the benefits of strawberries to another fruit, you can use statistic. For example, the amount of vitamin C contained in 250 grams of strawberries is equal to vitamin C contained in 500 grams of oranges.
By using statistic, the audiences will know that strawberries contain more benefits for their health. That is why they will be interested to buy strawberries after attending to your presentation.
3. Describing the background of data
You must heard news about surveys held by some institutions to count vote on last election event. In that news, it was described that candidate A has more chance to win the election compared to candidate B or the electability of candidate A decreases compared to former surveys.
Those surveys use statistics. They do not do survey to everyone, but only to some people who are considered representing a population. The data they got are considered representing what happens to the whole population, because they do the survey by using certain methods.
Statistic is required in many divisions, including in delivering a presentation. Statistic helps you to deliver information to audiences. You will be able to deliver it more easily.
A data visualization editor named Alan Smith delivered in a presentation that although not giving the exact thing, statistic can help people understand more easily.
Here is the presentation delivered by Alan Smith:
In his presentation, Smith said, “Statistics can give us a rich and surprising view of the everyday world around us.” With statistics, someone can see the difference between what he thinks with the reality.
According to smith, statistics is the science of us. By looking at the statistic data about things around us, the audiences will feel more connected with the material you deliver.
One thing you need to do is make the statistic display interesting while you deliver it. Although the data are usually numbers, but if you can deliver it properly, those numbers will not be boring. Your presentation will also be more spectacular.
