There is no significant difference between [define the two groups] on [dependent variable]. For example‚ "There is no significant difference between males and females on interest in reading." If there are three or more groups‚ then the research hypothesis should be slightly rephrased. An example is socioeconomic status whereby children are placed into three socioeconomic status groups: high‚ medium‚ and low. Instead of defining all three groups‚ state that there is no significant effect of the variable:
Premium Hypothesis Reading Experiment
empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement)‚ the results aiming to support or contradict a theory. The steps of the scientific method go something like this: Make an observation or observations. Ask questions about the observations and gather information. Form a hypothesis — a tentative description of what’s been observed‚ and make predictions based on that hypothesis. Test the hypothesis and predictions in an experiment that can be reproduced

fall at the same‚ or different‚ rates in the air and in a vacuum. Before you conduct your experiment‚ you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. Record your hypothesis here: If two objects fall at the same height then the object with the greatest mass will fall to the ground first.

Cars were exceptionally important in everyone’s daily lives. With the invention of cars‚ people had a means of transportation and saved a lot of time. However‚ in the beginning‚ cars were a pain to put together. The process of creating an automobile was costly and time consuming‚ because manufacturers did not have an easy way to put the vehicles together. It took half a day just to put one car together. However‚ all of that changed when Henry Ford came along. Henry Ford‚ born on July 30‚ 1863‚ in

Methods/Procedures To test the original hypothesis‚ six observations were taken at many different times during the day. Observations were taken during the morning‚ mid-afternoon‚ and the evening. The data was collected on four different days. To make sure that the observations would be consistent and accurate‚ two sets of observations were taken around in the same time frame. The location and the weather were constant‚ while the time of day was altered since it was the variable that was being tested

Title: Looking at fibres Aim: To investigate natural and synthetic fibres under the microscope. Hypothesis: I predict that natural fibres will appear rough and taper under the microscope and synthetic fibres will appear smooth. Method: Refer to text book 1‚ 2-2 fibres and fabrics. Results: Fabric sample to touch Description/observation 1. Silk Soft 2. Leather Soft 3. Corduroy Soft‚ rough underside 4. Nylon Soft‚ stretchy 5. Linen Soft 6. Wool Soft‚ rough‚ fluffy 7. Polyester

EXERCISE #1 Examine the table. Based on the information in Table 2‚ what patters do you observe? Develop a hypothesis related to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. What would your experimental approach be to test this hypothesis? What would your experimental approach to be to test this hypothesis? What are the independent and dependent variables? What would be your control? What type of graph would be appropriate

You don’t need to research for this. You just have to guess. Make sure it is accurate and clear. 5. Plan your experiment. Your experiment will confirm your hypothesis. Make sure the experiment will answers or really confirms the hypothesis. 6. Plan your materials. You will need on your experiment. Make sure they are easy to buy

attempts to explain the observation ex: why is this happening. * * Hypothesis: a statement made to predict the solution and outcome. * * Prediction: based on the hypothesis‚ indicates the outcome. It is an IF-THEN statement. * * Conclusion: details the findings of the testing. What happened when you tested your theory? * * Results: the result is tied back to the hypothesis. Is the hypothesis refuted or supported? If the findings are refuted then ask another question
