researchers were interested in the effects of cannibis and ecstacy on abstract thinking.Participants were given a task that required them to solve problems/tasks using abstract thinking.Researchers also included a group of nonusers. Base on the scenario, identify the Idependent variable and the dependent variable. Is the IV a quasi or experimental?. what is the research question.

Researchers were interested in learning the effects of trans fats on levels of cholesterol in the blood. Two different research designs were constructed. Part I: Between-Groups Design In the between-groups design, researchers were interested in whether cholesterol levels would differ depending on diet. Twenty participants were randomly assigned to one of two different groups. Group A was assigned a diet rich in fruits and vegetables and with no trans fats. Group B participants were asked to follow their normal diets,...

Researchers were interested in comparing the long-term psychological effects of being on a high-carbohydrate, low-fat (LF) diet versus a high-fat, low-carbohydrate (LC) diet. A total of 106 overweight and obese participants were randomly assigned to one of these two energy-restricted diets. At 52 weeks, 32 LC dieters and 33 LF dieters remained. Mood was assessed using a total mood disturbance score (TMDS), where a lower score is associated with a less negative mood. A summary of these results follows. Group...

consider the following research situation: A group of researchers is interested in study the effects of caffeine on memory. They plan to use a sample of 25 adults, with the intention of generalizing the findings to the larger population. One of the researchers is concerned, however, because their sample appears to differ from the population in regards to a characteristic that he believes could hinder the generalization of the caffeine and memory study results. This characteristic is cortisol level. A...

Suppose researchers interested in the effects of adolescent exposure to mold in a household is associated with asthma. Researchers collected information about a sample of children living in homes determined to have a significant amount of potential mold exposure and determined that 154 out of the 213 children had asthma. After a sample of 428 households with not a sufficient amount of mold exposure, only 108 children were found to have asthma. A) Conduct a statistical test to determine if...

Researchers are interested in how environment and interaction effects influence intelligence. In a colony of laboratory rats that are reared in an enriched environment (e.g. they have a varying number of toys, problem-solving activities, and food options) the variance in maze-solving time amongst individual rats is 5 min2. From this colony, they have also derived three inbred lines for low, medium and high intelligence. When individuals from these different inbred lines are reared together under strict uniform laboratory control conditions...

Researchers were interested in the relationship between mental health and living with a pet. Students were surveyed and grouped by pet type as either “Cats”, “Dogs”, or “No Pets”, and completed a scale on depressive symptoms on a scale of 1-7, where 7 indicates high levels of depressive symptoms. Using the data in the frequency table below, please conduct a one-way ANOVA to determine if there are any significant differences between these groups. Use α = .05, report η², and...

Q1. Researchers were interested in determining whether there were any differences in the tendency to procrastinate based on birth order, i.e. first, second, or third child born. Using the data in the table below, answer the following questions. State the null and alternate hypotheses. What is the total sample size? Identify the independent and dependent variables What is the test statistic value? What is the p value? What is your conclusion (assume α = .05)? Phrase your conclusion based on...

In this study, researchers were interested in knowing if the amount of coffee (none, one cup, 4 cups) and the time coffee was ingested (am v. pm) affected student exam performance (exams were in the evening). This study took place over a 3-day period. Students were randomly assigned to either ingest coffee in the morning (AM) or the evening (PM). On day one, students were given no coffee; on day two, students were given one cup of coffee; and on...

Researchers were interested in the relationship between the number of hours per week on Facebook and perceived loneliness (higher the score, the lonelier the individual) in older adults. Using the tables below, answer the following questions. Is there a significant relationship time spent on Facebook and perceived loneliness? Explain your answer. Write out the regression equation. Given the calculated regression equation (see question 6), calculate Y' for each of the following values of X: 10 15 25 Regression...
