Document Summary
Analyzing and interpreting data to test the hypothesis. Allows us to draw cause-and-effect conclusions about particular variables or events. Statement about the cause of an event or about the relationship between two events. Independent and dependent variables (look at examples?) Correlation studies the relationship between iv and dv. 1 = perfect relationship; -# = moderate; 0 = unrelated. Involves one person or sometimes a small group examined under certain conditions. Studying something over a long period of time. Examining different groups of people at one point in time. Can begin as a cross-sectional study as groups are examined over a. Internal validity ->how much the iv affected the dv. External validity ->these results generalize to a larger group than just this one group of people. An emotional state that occurs as a threatening event draws close. Worry is largely cognitive or thought concept. Survival need anxiety to fear things that could hurt you/kill you.
