1. To formulate a hypothesis for this investigation, you need to consider your research question or problem statement. A hypothesis is an educated guess or prediction about the relationship between variables. It should be based on prior knowledge or observations. For example, if you are investigating the effect of temperature on plant growth, your hypothesis could be: "Increasing temperatures will enhance plant growth rates."
2. The aim of the investigation is to clearly state the purpose or objective of the research. It should describe what you want to accomplish or learn from conducting the investigation. For instance, the aim of the investigation in our previous example could be: "To determine the impact of different temperatures on plant growth and identify the optimal temperature range for maximum growth."
3. a) The independent variable is the variable that you deliberately manipulate or change in the experiment. In our example, the independent variable would be the temperature because different temperatures are being tested to observe their effect on plant growth.
b) The dependent variable is the variable that is measured or observed as an outcome of the experiment. It is affected by the changes in the independent variable. In our example, the dependent variable would be the plant growth, as it is influenced by the different temperatures applied.
c) Controlled variables are the variables that are kept constant or maintained at the same level throughout the experiment. They are not allowed to change, as any variation in these variables could lead to unreliable results. In our example, controlled variables could include factors like humidity, soil type, light exposure, and nutrient availability, which should be kept constant across all the experimental conditions.
4. The methods and control refer to the procedures and conditions implemented to conduct the experiment and ensure the reliability of the results. This includes the following aspects:
- Experimental Design: Describe how the experiment will be set up, including the number of samples, replicates, and control groups. This ensures that the experiment is well-structured and can yield accurate results.
- Data Collection: Specify the measurements or observations that will be recorded during the experiment to quantify the dependent variable. This ensures that the data collected is relevant and can be used for analysis.
- Control Group: Assign a control group that does not receive the manipulation of the independent variable. This provides a baseline for comparison to measure the effects of the independent variable accurately.
- Randomization and Replication: Randomly assign the treatment groups to avoid bias and ensure a representative sample. Repeat the experiment multiple times to increase the reliability of the results.
- Data Analysis: Describe the statistical methods or analysis techniques that will be used to analyze the data and draw conclusions. This ensures that the results are interpreted objectively and can be validated statistically.
