What are the 3 types of studies?

1. C

2. C

3. E

Lets Get Started..

Decide what you want to know about

Then….

FORUMLATE A HYPOTHESIS

A CLEARLY DEFINED STATEMENT OF

EXPECTED RESULTS.

EDUCATED GUESS…

TEST HYPOTHESIS

Determine the best method to use to test your hypothesis and then develop your procedures.

Determine if you need an experimental group and one or more control groups.

EXPERIMENTAL METHOD

You’ll need two different groups..

Experimental group-receives the independent variable

Control group- does not receive the independent variable

If………..(independent variable)

Then……….(dependent variable)

EXAMPLE

STRICT PARENTS RAISE CHILDREN WHO RARELY GET IN TROUBLE.

Agree / Disagree

The independent variable is the “if” part of the experiment

The dependent variable is the “then” part of the experiment-what you are

measuring.

MY HYPOTHESIS

Your hypothesis… parents and how they raise children…

WRITE ONE NOW…

IF..

THEN..

Placebo

Sometime a placebo is used in experiments

What's that??

Why?? Attempt to control other variables

Placebo

The POWER of SUGGESTION…

Hypochondriacs…

EXPERIMENTAL GROUP

EXPOSED TO THE

______________

WHAT YOU ARE TESTING

Control Group

______ EXPOSED TO THE

INDEPENDENT VARIABLE

SCENERIO

AT 3:00 A.M. IN NYC, KITTY GENOVESE WASATTACKED ON THESTREET IN FRONTOF HER APARTMENT. IT TOOK THE MAN OVER 30 MINUTES

TO MURDER HER.

38 NEIGHBORS STOOD AT THEIR WINDOWS

SHE SCREAMED FOR HELPOVER AND OVER AGAIN.

NO ONE HELPED HER ORCALLED THE POLICE.

FINALLY, ONE NEIGHBORCALLED THE POLICE, BUT IT WAS TOO LATEFOR KITTY.

What is your hypothesis?

HYPOTHESIS IS…

PONDER…IN A GAME OF CATCH, THE WAY THE BALL IS

THROWN WILL AFFECT WHETHER THE BALL IS CAUGHT.

STUDENTS SCORE HIGHER ON ACT TESTS IN THE MORNING THAN IN THE AFTERNOON

HYPOTHESIS???

Additional Methods

LABORATORY EXPERIMENT

FIELD EXPERIMENT

SURVEY METHOD

NATURALISTIC OBSERVATION

INTERVIEW

PSYCHOLOGICAL TEST

MORE ACCURATE, OBJECTIVE DATA

PSYCHOLOGICAL TEST OFTEN COMBINED WITH THE INTERVIEW

PROVIDE SUBJECTIVE ANDOBJECTIVE PERSPECTIVE.

CASE STUDY METHOD

LONGITUDINAL METHOD

CROSS-SECTIONAL

LESS EXPENSIVE AND TIME-

CONSUMING THAN THE LONGITUDINAL METHOD.

NOT APPROPRIATE FOR STUDIES ONDEVELOPMENT OVER TIME.

CAN YOU TRUST THOSE POLLS

What do you think???

From what you now know about the standards of research studies, find out as much as you can about any study or poll that you read about in a newspaper or magazine.
