Statistics

A

A collection of numerical data

44

51
Q

52
Q

Identify 3 goals of the scientific enterprise

A
  1. Measurement/ description
    - develop techniques to observe behaviour
  2. Understanding/ prediction
    - you can only fully understand events once you know why they happen
  3. Application/ control
    - apply research to practical problems such as those in schools, businesses and hospitals
53
Q

List 5 steps in scientific investigations

A
  1. Formulate a testable hypothesis
  2. Select research method and design the study
  3. Collect the data
  4. Analyze the data and draw conclusions
  5. Report findings
54
Q

List 2 advantages to the scientific approach

A
  1. Precision and clarity

2. Relative intolerance for error

55
Q

Why is is advantageous to sometimes only use one group who works as their own control?

A

Having one group gets rid of any extraneous variables such as personal ability

56
Q

Q

Symmetrical Frequency Distribution

A

Mean, median and mode all match up

58
Q

Negatively Skewed Distribution

A

All scores pile up on the higher end of the scale

59
Q

Positively Skewed Distribution

A

All scores pile up on the lower end of the scale

60
Q

Percentile Score

A

Percent of people who score at or above a certain score
