Define Range of Instrument
Definition:
Set of values of quantities of the same kind that can be measured by a given measuring instrument or measuring system with specified instrumental uncertainty, under defined conditions. Or simply we can say that range of measuring instrument is maximum or minimum value an instrument can measure.
Example:
The range of voltmeter is 250 volts. This means we can measure maximum 250 volts using that meter or we can apply just 250 volts across the probes of that meter.

Range of Instrument
The values between the minimum measurable value and the maximum value that can be measured called the range of the instrument.
For example,the range of the scale is zero centimeter to thirty centimeters.Usually, we state the maximum value as the range since the minimum value is generally zero.When we say, the range of the metre scale is 100cm, we mean that the range is from zero to 100cm.

Comparing Order of Magnitudes
An order-of-magnitude difference between two values is a factor of .
For example: The mass of the Sun is million times that of the Earth, so Saturn is 6 orders of magnitude more massive than Earth.

Scientific method steps
- Make an Observation: Scientists are naturally curious about the world. Many people may ignore a curious phenomenon. But scientists think over it.
- Form a Question: After making an interesting observation, a scientific mind wants to find out more about it. This is in fact a natural phenomenon. If you have ever wondered why or how something occurs, you have been listening to the scientist in you.
- Form a Hypothesis: A hypothesis is a guessed answer of the question. The hypothesis may be formed as soon as the question is posed, or it may require a great deal of background research and inquiry. The purpose of the hypothesis is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.
- Conduct an Experiment: Once a hypothesis has been formed, it must be tested. This is done by conducting a carefully designed and controlled experiment.

Understanding conclusion and finding of an experiment
Analyse the Data and Draw a Conclusion: As the experiment is conducted, it is important to note down the results. In an experiment, it is necessary to conduct several trials to ensure that the results are constant. The experimenter then analyses all the data and uses it to draw a conclusion regarding the strength of the hypothesis. If the data proves the hypothesis correct, the original question is answered. On the other hand, if the data disproves the hypothesis, the scientific inquiry continues by doing research to form a new hypothesis and then conducting an experiment to test it.

Different types of tabular forms
A tabular form is a multi-record form that enables you to view multiple records from a table and edit them. Each record is displayed as a single row in the tabular form and each field is displayed as a column, creating a table within the form itself. Tabular forms are named after the table with which they are associated only in plural. For example, the tabular form associated with the country/region table is called Countries/Regions. In the case of associated tables that have multiple fields in the primary key, the name can be different. For example, the tabular form associated with the general posting setup table is called General Posting Setup.

Presentation of data in a tabular form
A tabular data presentation is the clear organization of data into rows and columns. The use of tables is pervasive throughout all communication, research and data analysis.
Definition
Advantages of presentation of data in a tabular form
- Data can be presented in condensed and simple form.
- Different types of data can be compared easily.
- It provides information about the problem in a simple and clear manner.
- It saves time and space as the data is presented in condensed form.
- It makes checking of data easier.
Definition
Presentation of data in a graphical form
The information can usually be presented in graphical form, which makes it easier to understand. Graphs tell a story with visuals rather than in words or numbers and can help readers understand the substance of the findings rather than the technical details behind the numbers.
Definition
Use of straight line graph in identifying proportional relationships
If two physical quantities are varying linearly and one quantity is increasing with increment in other , then they are said to be in a proportional relationship.
For example according to Ohm's law
Here Voltage and Current has linear relationship and hence they have straight line graph.
