(in your own words)

Self fulfilling prophecy- when someone beliefs in something and it turns out to be right, this proves people’s beliefs influence their actions.

Single blind experiment- an experiment in which only one person (the participant or the experimenter) knows tho is receiving a particular treatment

Double blind experiment - an experiment in which neither the participants nor the experimenters know who is receiving a particular treatment

placebo effect- a beneficial effect, not caused by the placebo itself, but caused by the patients belief in the treatment.

Statistics- a organized display of data

descriptive statistics- a summary statistic that quantitatively describes or summarizes features of a collection of information, while descriptive statistics in the mass noun sense is the process of using and analyzing those statistics.

frequency distribution- tells how frequencies are distributed over values, frequency distributions are mostly used for summarizing categorical variables.

Normal curve- a very common continuous probability curve. Normal curves are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose curves are not known.

Central tendency- a central or typical value for a probability distribution.

Variance- being different, divergent, or inconsistent.

Standard deviation- a quantity calculated to indicate the extent of deviation for a group.

Correlation coefficient- a numerical measure of some type of correlation.

Inferential statistics- the process of using data analysis to deduce properties of an underlying probability distribution.
