From the diagram:
1. Is A responding variable?
2. Is B manipulated variable?
3. Is C controlled variable OR constant?
* This diagram all I'm given for this question; there is no clarifications on what A,B,C are pointing to...
Consider the variables: A, B, C, D, E, F, G, and H.
A and B, B and C, C and D are directly related while D and E, E and F, F and G, and G and H are inversely related. If an initial increase occurs in the value of A, the value of H will
a. decrease
b. increase
c. stay the same
d. cannot predict from the given information

- The purpose of the constant is to: a. allow for adjustment of the control b. eliminate other potential factors/variables in the experiment c. allow for the dependent variable to show the necessary outcome d. help prove the hypothesis correctarrow_forwardVariables are used not only in research and studies but are also often used in everyday life. Knowing the difference in variables can help you make life decisions. There are several different types of variables but the two main ones are independent variables and dependent variables. why are independent variables so important?arrow_forwardWhich of these factors is commonly manipulated during an experiment? independent variable dependent variable controlled variable continuous variable When carrying out an experiment, a scientist will observe changes in which factor? confounding variable dependent variable controlled variable independent variable Which of these factors remains intentionally unchanged in an experiment? controlled variable continuous variable independent variable dependent variablearrow_forward
- In an experiment, the control group is used to: a Change the variable b Provide a baseline for comparison with the test group c add additional non-dependent variables d demonstrate correlation rather than causation e generate hypothesesarrow_forwardwhat is the Expectation and outcome of results, Logical interpretation of the dataand any errors?arrow_forwardan independent variable is the variable measured in an experiment. True or Falsearrow_forward
- In the context of the Chi-square analysis, the null hypothesis states that _________________________. the differences between the measured values and the predicted values are too large to allow us to attribute them to chance the differences between the measured values and the predicted values are not significant and can be attributed to chance the measured values are too small to allow a prediction to be made there should be no numerical difference between the measured and the predicted values None of the other answers are correct.arrow_forwardWhat is the definition of independent variable , dependent variable, and constant? Where on a graph do the independent and dependent variables appear? What is the definition of a law? What does the conclusion state in an experiment? Does a theory become true after one experiment? At what temperature in both Celsius and Fahrenheit does water boil and freeze?arrow_forwardWhich of the following are variable terms in the discrete-time logistic model? ΔN Δt rmax,d t Nt K None of thesearrow_forward
- I am testing the prediction that spiders with colors that match a flower (cryptic coloration) will have greater success hunting bees visiting that flower. I set up two treatments for spiders: those matching their flower and those not matching their flower. I measure how long it takes each of them to catch a bee. What kind of statistical test would be best for testing my prediction?
