Professor Gonzalez is interested in evaluating the ability of a new method of note-taking to improve student grades. Group A is trained in the new method and group B uses the traditional outline method of taking notes. What is Professor Gonzalez independent variable?

Method of note taking

In developmental psychology, one advantage of cross-sectional over longitudinal studies is that cross-sectional research

requires comparatively little time

The scientific experiments includes the different steps used for the validation of any hypothesis. The experiments can explain the main cause of any phenomena and the factors that might affect the experiments. The experimental studies are performed by the scientists.

Conduct an experiment

According to wilhem wundt, the focus of scientific psychology should b the study of

Conscious experience

Survey shows that children who have encyclopedias in their homes get better grades opposed to those who don't, research concludes that encyclopedias at home improve grades. Why is this research unable to make this conclusion?

Inferred causation from correlation

a double-blind control is essential for which of the following?

assessment of a treatment designed to reduce schizophrenic symptoms

a researcher surveyed social adjustment in the same group of 20 people from early childhood through adulthood. in this example, the group of 20 people surveyed was the study's ?

sample

standard deviation is a measure of how much

scores in a group differ from the mean of that group

The results of a correlational study involving student volunteers in a psychology laboratory might not apply to the general population because

the sample is not randomly chosen and therefore may not be a representative sample

A teacher finds the distribution of scores on a final exam to be positively skewed with low variability. On the basis of this information, the teacher would be most justified in concluding that the exam was too

Hard

According to one theory of psychology, many people have mental illnesses because their maladaptive behaviors have proven rewarding for them in the past and thus have been continued. This belief is consistent with which of the following models?

survival

Professor Ahad has forty-three students in section one of the psychology classes she teaches and fifty-two students in section two. Section one meets at eight a.m. and, section two meets at one p.m. Professor Ahad gives all of her students the same final exam, and those in section two score significantly higher than those in section one. Professor Ahad concludes that her section one students are academically inferior to students in section two. The biggest problem with Professor Ahad's conclusion is that

time of day is a confounding variable in this scenario.

In an experiment designed to determine whether watching violent scenes on television increases the frequency of aggressive behavior in children, one group of subjects saw a nonviolent cartoon and another group saw a violent cartoon. In the play period that followed the viewing of the cartoons, researchers observed the two groups of children together and counted instances of aggressive behavior. The control group in the experiment is the group that

watched the nonviolent cartoon
