Part a
start by creating two different circles:
create a point, and label it a. to make the remainder of the activity easier, choose integers for the x and y coordinates of point a.
create a circle with its center at point a and with a radius of your choice. to make the remainder of the activity easier, choose an integer value for the radius.
create another point, and label it b. to make the remainder of the activity easier, choose integers for the x and y coordinates of the point.
create a circle with its center at point b and with a radius of your choice that is different from the radius chosen for circle a. to make the remainder of the activity easier, choose an integer value for the radius.
part b. recall what you know about similarity. if circle b is similar to circle a, what must exist?
part c. what is the difference of the x-coordinate of point a and the x-coordinate of point b?
part d. in terms of rigid transformations (reflections, rotations, and translations), what does this difference represent?
part e. what is the difference of the y-coordinate of point a and the y-coordinate of point b?
part f. in terms of rigid transformations (reflections, rotations, and translations), what does this difference represent?

Study published in the journal of personality and individual differences found that adults with adhd displayed more creative achievement than those who didn't have the disorder. "for the same reason that adhd might create problems, like distraction, it can also allow an openness to new ideas," says holly white, assistant professor of cognitive psychology. "not being completely focused on a task lets the mind make associations that might not have happened otherwise." white and priti shah at the university of michigan gave 60 college students – half of them with adhd – a series of tests measuring creativity across 10 domains. the adhd group scored higher across the board. the adhd group showed more of a preference for brainstorming and generating ideas than the non-adhd group, which preferred refining and clarifying ideas. the adhd status of the participants was established by asking whether the individual had ever been clinically diagnosed with adhd/add. the tests of creativity were pencil-and-paper tasks administered in a laboratory setting. each of the ten scales was comprised of multiple questions, the scores on which were summed (e. g., writing creativity: "how many words can you make from the letters in the word 'psychology' invention creativity: "write down as many uses for a paper clip that you can think of.") this procedure does allow for a participant to be scored as showing no creativity under these conditions. a) state the research question in plain language (i wonder if is related to (1 point) b) state the null hypothesis (1 point) c) state the research hypothesis (1 point) d) is the research hypothesis directional or non-directional (1 point) e) name the predictor / independent variable f) give the operational definition of the predictor / independent variable g) evaluate the construct validity of the predictor / independent variable. (face, procedure, method-match) h) name the outcome / dependent variable i) give the operational definition of the outcome / dependent variable. j) evaluate the construct validity of the outcome / dependent variable.
