"NEW TECHNOLOGIES & NEW THINKING DEFINE THIS ERA"

 MY EXPERIENCE 

"It was a great experience "😊😊.I learned and practiced something....... something about information technology.............Actually i was very scared about πŸ˜”πŸ˜”πŸ˜”this workshop because i am not able to handle new information technologies very well. From the very first day , i listened carefully .I learned that i am able to do the particular work alone ,and i can also help my friendsπŸ˜†.So gradually my confidence level started to increase .It was a positive sign for over coming my inhibition😊😊😊😊😊 .Our dear SAJAN SIR strives to mold us in to well trained professionals capable of handling the new technical skills that are increasingly relevant  in todays digital age. I don't know we have reached the level that sir expects........But majority of us are confident in applying this information to our profession.

                                       I wanted to express my sincere gratitude for SAJAN SIR'S invaluable support in the ICT workshop. Your guidance has made a significant impact on my under standing and has fueled my passion for technology. Thankyou for  being such a  dedicated and inspiring teacher.....................

HYPOTHESIS

 

 

 HYPOTHESIS

A hypothesis is a specific, testable prediction. It describes in concrete terms what you expect will happen in a certain circumstance. Most researches come up with a hypothesis statement at the beginning of the study. A good hypothesis must possess the following characteristics. It is never formulated in the form of a question. It should be empirically testable, whether it is right or wrong. It should be specific and precise.

Functions Of Hypothesis

Following are the functions performed by the hypothesis: Hypothesis helps in making an observation and experiments possible. It becomes the start point for the investigation. Hypothesis helps in verifying the observations. It helps in directing the inquiries in the right direction

How Will Hypothesis Help In The Scientific Methods?

Researchers use hypotheses to put down their thoughts directing how the experiment would take place. Following are the steps that are involved in the scientific method: Formation of question, doing background research, Creation of hypothesis, Designing an experiment, Collection of data, Result analysis. A hypothesis is a proposed explanation for a phenomenon. It is an educated guess or statement that can be tested through research. Hypotheses are essential for scientific inquiry, as they provide a framework for designing experiments and interpreting results.

There Are Many Different Sources Of Hypotheses. Some Of The Most Common Include.

Previous research. This is one of the most common sources of hypotheses. Researchers often review the literature on a topic to identify gaps in knowledge or areas where there is disagreement. This can lead to the development of new hypotheses that can be tested.

Observations. Researchers may also develop hypotheses based on their own observations. For example, a researcher who notices that a particular plant seems to grow taller when it is exposed to more sunlight may develop the hypothesis that sunlight promotes plant growth.

Analogy. Researchers may also develop hypotheses based on analogies to other phenomena. For example, a researcher who is studying the spread of a disease may draw an analogy to the spread of a wildfire. This analogy could lead to the development of hypotheses about how the disease spreads. Here are some additional sources of hypotheses:

Personal experience. A researcher's own experiences can sometimes lead to the development of hypotheses. For example, a researcher who has experienced a particular medical condition may be more likely to develop hypotheses about that condition.

Serendipity. Sometimes, hypotheses are developed by accident. For example, Alexander Fleming discovered penicillin by accident when he noticed that mold was preventing the growth of bacteria.

Cultural influences. The cultural background of a researcher can also influence the development of hypotheses. For example, a researcher who comes from a culture that places a high value on education may be more likely to develop hypotheses about the relationship between education and success.

Features of hypothesis

Figure 1 shows the features of hypothesis

 


 

Type of hypothesis

Table 1

Null hypothesis

States that there is no significant relationship or difference between variables.

Alternative hypothesis

Contracts with the null hypothesis and proposes a specific relationship or difference between variables.

Directional hypothesis

Predicts the direction of the relationship between variables.

Research hypothesis

A specific statement that proposes a relationship or difference between variables based on theoretical evidence.

Descriptive hypothesis

Used to describe or characterize a particular phenomenon or behaviour.

 

Table 1 shows different types of hypothesis and its description

          No matter what the source, a good hypothesis should be

Testable. A hypothesis must be able to be tested through research. If a hypothesis cannot be tested, it is not useful.

Falsifiable. A hypothesis must be able to be proven wrong. If a hypothesis cannot be proven wrong, it is not scientific.Specific. A hypothesis should be specific enough to be tested. A vague hypothesis is not useful.Relevant. A hypothesis should be relevant to the research question. A hypothesis that is not relevant is not useful.Parsimonious. A hypothesis should be the simplest explanation that fits the data. A complex hypothesis is not as likely to be correct as a simpler hypothesis.The development of a good hypothesis is an important step in the scientific process. By carefully considering the sources of hypotheses, researchers can develop hypotheses that are more likely to be correct and lead to new discoveries.
