Recording and Presenting Data
Recording Data
- Data means any number that you read from a tool. This includes temperature, mass, volume, etc.
- Always record the units of measure (deg C, grams, etc).
- Every tool has a smallest marked division. Most of our thermometers have a mark every 1 degree. When recording data, make sure to record all of the numbers marked, and one more digit that you estimate. On our thermometers, this means record to the 0.1 deg C. It's up to you to estimate this last number; if you think it's "on the line" then you are estimating a "0".
- Record the numbers when you read them. Don't put the zeroes in later, and don't memorize the number to write it down somewhere else. Bring your notebook with you!
- Record the numbers exactly as you read them. If you are looking at the age of a penny, write the year it says (1998), not the age (2 years). Any number that you have to calculate is a result, not data.
Presenting Data
- Data should always be presented in columns in a data table. The table must have a title or heading.
- Every piece of data should be named (ex. "mass of cold water")
- Every piece of data should have a number (ex. "23.718")
- Every piece of data should have a label (ex. "grams")
- If there are many measurements of the same type, you can name them in the column heading, rather than individually. The same is true for the labels.
- Always line up the decimal points in the column of numbers. This can be done using decimal-aligned tabs, or presenting data tables in a font such as Courier (where each letter gets the same width).
- Spread it out! Don't be afraid to make your data table as wide as the page. You can align the decimals on the red margin line you can see through the page.
- Relevant observations should be included with data.

What are the two ways of presenting a data?
There are numerous ways of presenting data. But if you have to narrow it two alternatives, I can only assume that they would be written and visually. A properly prepared scientific report uses both a written section describing the data in word form and also various tables and possibly diagrams to visually describe the data.
What are the two ways of presenting data?
Tables and Graphs. Audio-visual is just one way.
What are the ways or forms of presenting data in statistics?

What is the one way of presenting data?
There is no one way of presenting data. There are good ways and there are bad ways. You must consider the nature of the data to decide the best way of presenting it. Consider that the famous nurse Florence Nightingale is credited with the first use of "pie charts" to illustrate medical data to non-medical persons. Human beings are very "visual" in nature, so choose the way of presenting data that gives the best impression of the principle you are trying to convey. Pie charts are best for presenting percentages, while line graphs are best for presenting trends, while raw numerical data may be best presented in a table with one quantity ascending/descending in value in the leftmost column. If using computer software such as Excel to present data, you will find a number of choices available in the Chart Wizard which allow you to provide the best visualization.
Definition of graphical presentation in statistics?
It is simply the presentation of information in a visual form. There are very many ways of presenting different aspects of data.
