STATISTICS
STUDY OF COLLECTION, ANALYSIS, INTERPRETATION, PRESENTATION, AND ORGANIZATION OF DATA
STATISTICS
MATHEMATICAL DISCIPLINE TO COLLECT AND SUMMARIZE DATA
STATISTICS
USED TO CONDUCT RESEARCH, EVALUATE OUTCOMES, DEVELOP CRITICAL THINKING, AND MAKE INFORMED DECISIONS
STATISTICS
MORE CONCERNED WITH THE CONCEPT OF RANDOMNESS
STATISTICS
PREOCCUPIED WITH MAKING DECISIONS
PROBABILITY
FIELD OF MATHEMATICS THAT DEALS WITH CHANCE
PROBABILITY
HOW LIKELY SOMETHING IS TO HAPPEN
PROBABILITY
RATIO OF NUMBER OF FAVORABLE OUTCOMES TO THE TOTAL NUMBER OF OUTCOMES OF AN EVENT
EXPERIMENT
ONLY PROCEDURE THAT CAN BE INFINITELY REPEATED, AND HAS A WELL DEFINED SET OF POSSIBLE OUTCOMES KNOWN AS SAMPLE SPACE
OUTCOME
RESULT OF AN EXPERIMENT
EVENT
COLLECTION OF OUTCOMES
SIMPLE EVENT
EVENT WITH ONLY ONE POSSIBLE OUTCOME
SAMPLE SPACE
REPRESENTS THE SET FOR ALL POSSIBLE OUTCOMES OF A RANDO M EXPERIMENT
DISCRETE VARIABLE
TALIES ONLY LIMITED OR A COUNTABLE NUMBER OF VALUES
DISCRETE VALUABLE
LIMITED, FINITE, COUNTABLE
CONTINUOUS VARIABLE
DEALS WITH RANDOM VARIABLE X WITH TALIE ANY VALUE BETWEEN CERTAIN INTERNALS
CONTINUOUS VARIABLE
MEASURED DATA, INFINITE, LOTS OF POSSIBLE VALUES
DISCRETE PROBABILITY DISTRIBUTION
TABLE, GRAPH, FORMULA, OR NOTATION, WHICH SUPPLIES THE PROBABILITY OF A GIVEN OUTCOME
1ST PROPERTY
BETWEEN 0 AND 1
1ST PROPERTY
THE PROBABILITY SHOULD ALWAYS BE LESS THAN 1, BUT NOT EQUAL TO 0
2ND PROPERTY
THE SUM OF ALL PROBABILITIES SHOULD BE EQUAL TO 1
3RD PROPERTY
NO NEGATIVE PROBABILITIES
HISTORGAM
VISUAL REPRESENTATION OF THE DISTRIBUTION FO QUANTITATIVE DATA
HISTOGRAM
CHART THAT PLOTS THE DISTRIBUTION OF A NUMERIC VARIABLE’S VALUES AS A SERIES OF BARS
HISTOGRAM
ALWAYS IN INCREASING ORDER
PROBABILITY MASS FUNCTION
PROBABILITY OF EACH SPECIFIC VALUE
MEAN
CONSIDERED AS A MEASURE OF THE CENTRAL LOCATION WEIGHTED AVERAGE OF THE VALUES THAT RANDOM VARIABLE X CAN TAKE
MEAN
MULTIPLY EACH X VALUES (RANDOM VARIABLE) BY ITS PROBABILITY AND ADD IT ALL
VARIANCE
MEASURE OF HOW SPREAD OUT DATA VALUES ARE FROM THE MEAN (AVERAGE)
NORMAL DISTRIBUTION
MATHEMATICAL MODEL REPRESENTED BY A BELL-SHAPED CURVE
EQUAL
MEAN, MEDIAN, MODE ARE ALL _______
MEAN
AVERAGE OF THE DATA
MODE
MOST REOCCURING VALUE
