- ____________ are often used to exemplify the relations that exist within a scientific experiment between the dependent and independent variables. Question 1 options: Ternary diagrams Rose diagrams None of the other answers are correct. Bar graphs Scatter plot graphs Line graphsAll of the following are possible steps of scientific investigation except for ____________. Question 7 options: None of the other answers are possible steps of scientific investigation. All of the other answers are possible steps of scientific investigation. development of observations and experiments to test the hypotheses the development of one or more working hypotheses or models to explain facts the collection of scientific facts through observation and measurement assumption of conclusions without prior experimentation or observationan independent variable is the variable measured in an experiment. True or False
- In the experiment described above, state what each of these parts of the experiment was: Independent variable Dependent variable Control group Experimental group One controlled variable___________ __________ is the precise repetition of an experiment or expansion of observed data to provide verification; the procedure by which hypotheses and theories are verified, modified, or discarded. Group of answer choices A-empirical hypothesizing B-pscientific testing C-theoretical investigating D-qualitative observing E-quantitative reasoningDesign a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it's real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state (hypothetical) 'actual' results and the appropriate conclusion to draw from those results.
- According to this experiment, summarize it and be sure to address the following questions: What hypothesis was being tested? How did you test your hypothesis? What independent and dependent variables were being investigated? What controls did you use? What were possible sources of error in your experiment? Please explain how the experiment you conducted supported or failed to support the original hypothesis.In the experiment described above, specifically state what each of these parts of the experiment was: Independent variable Dependent variable Control group Experimental group One controlled variableA useful hypothesis typically accomplishes these two things: Group of answer choices it is falsifiable and clear it clearly establishes a null hypothesis and it generates a testable prediction it can be easily disproved and will be considered a theory if not disproved it frames an experiment that can shed light on the observation and guides design of the experiment
- Question 7Which of the following is the correct sequence of steps in the scientific method? Question 7 options: Form a theory, conduct an experiment, develop a hypothesis, and make an observation Conduct an experiment, develop a hypothesis, form a theory, and make an observation Make an observation, develop a hypothesis, conduct an experiment, and form a theory Develop a hypothesis, conduct an experiment, make an observation, and form a theoryof Skill 3: Identifying Types of Data Sys Hypotheses are tested by evidence collected in the form of scientific data, or information obtained using specific analytical methods as part of an experiment or empirical observation. Scientific data can be qualitative or quantitative. Quantitative data are expressed as numeric values, rendering observations more objective and quantifiable, and can be either discrete of continuous. Discrete data can only take certain values (such as whole numbers), whereas continuous data can take any value mei within a range and can be represented by fractions and decimals. Qualitative, or categorical, data are descriptive, pertaining to properties that are difficult or impossible to express numerically, such as aspects of behavior or complex shape.
