Question
Please write “true” if the statement is true and “false” is the statement is false in the space provided:
26. In the following hypothesis: “Nicotine will have an effect on memory,” the dependent variable is nicotine ______27. In the following hypothesis: “Nicotine will have an effect on memory,” the independent variable is memory ______28. Researchers collect data by measuring the dependent variable in their studies ______29. Independent variables are the variables that researchers manipulate in their studies ______30. In a directional (one-tail) hypothesis test, the entire critical region is located in either one of the other tail of the distribution, but not in both tails of the distribution ______31. The reason for computing Cohen’s d is that a hypothesis test, per se, does not measure the size of the effect ______32. Cohen’s d or any other “d” measures effect size ______33. Standard error is the discrepancy or difference, on average, that you should expect between your sample mean (M) and the population mean (µ) ______34. All hypotheses tests analyze (or compare) two main differences. These differences are the differences between or among means due to the IV, and difference between or among means due to chance.

Explanation / Answer
26. We are given Memory is a function of Nicotine hence dependent variable is Memory and independent variable is Nicotine hence False
27. As discussed above Memory is dependent or response variable hence False
28. Researchers collect the data of independent variable and using the function see the effect of the independent or explanatory variable to see how it effects the dependent variable( Memory)
Hence false
29. Independent variables can be manipulated by reserchers to get a better relation between the independent and dependent variable hence True
30. In a one tail test the entire critical region is located on only one side but not both tails hence true
31.Cohens d is effect size which is used to measure standardised difference between 2 means hence False
32 As discussed in point 31 Cohens d is effect size hence true
33.Standard error tells us the dispersion of sample mean around the population mean hence true
34. Hypothesis testing begins with an assumption for the null hypothesis H0 which challenges the alternate hypothesis H1
Using both the H0 and H1 we take a sample data and check if the difference found is because of chance or because of statistical significance in the independent variable( IV) data
Hence the statement is true
