Presentation Transcript

Simulations are used by engineers, programmers, and other scientists to produce the probable results of an experiment or happening.


Coming events
COMING EVENTS scientists to produce the probable results of an experiment or happening.

  • SIMULATIONS IN GAMES.

  • SIMULATIONS OF EVENTS OR FUTURE ACTIONS.

  • SETTING UP SIMPLE SIMULATIONS

  • ADVANCED SIMULATION –MONTE CARLO METHOD.


Focus and inquiry
FOCUS AND INQUIRY scientists to produce the probable results of an experiment or happening.

  • WHAT IS YOUR FAVORITE VIDEO OR COMPUTER GAME?

  • WHAT DOES THIS “GAME” HAVE TO KNOW TO PLAY?

  • WHAT STATISTICS ARE USED?

MAJOR LEAGE BASEBALL scientists to produce the probable results of an experiment or happening.SAMMY SOSA EDITION

  • WHAT ARE THE STATISTICS FOR THE PITCHER: ERA, STRIKEOUT RATE…

  • WHAT ARE THE STATISTICS FOR THE BATTER: BATTING AVERAGE, HOW BATTER DOES AGAINST CERTAIN PITCHER…

  • IS THE BAT CORKED?


Game simulation
GAME SIMULATION scientists to produce the probable results of an experiment or happening.

  • THE COMPUTER TAKES ALL OF THE INFORMATION (IN STATISTICAL FORM AND CALCULATES THE PROBABILITY OF AN EVENT HAPPENING.

  • THE COMPUTER WILL CHOOSE WHAT WILL HAPPEN TO THE PLAYERS BY PROBABILITY.


Simple simulation
SIMPLE SIMULATION scientists to produce the probable results of an experiment or happening.

SITUATION:

  • THE LAKERS ARE ONE POINT BEHIND.

  • SHAQ IS FOULED WITH NO TIME LEFT ON THE CLOCK (TWO FREE THROWS)

  • RUN 25 SIMULATIONS AND GIVE RESULTS


Possibilities
POSSIBILITIES scientists to produce the probable results of an experiment or happening.

  • MAKES NO SHOTS—LOSES GAME

  • MAKES ONE SHOT—TIES GAME AND INTO OVERTIME

  • MAKES TWO SHOTS—WINS GAME


Statistical information
STATISTICAL INFORMATION scientists to produce the probable results of an experiment or happening.

  • SHAQ IS A 63% FREE THROW SHOOTER

  • NO OTHER STATISTIC IS NEEDED AT THIS TIME.


Setting up a simulation on the ti 83

SETTING UP A SIMULATION ON THE scientists to produce the probable results of an experiment or happening.TI-83+


Using the prob sim application
USING THE PROB/SIM APPLICATION scientists to produce the probable results of an experiment or happening.

  • CHOOSE RANDOM NUMBERS

  • DRAW TWO

  • RANGE: 0-99

  • REPEAT YES

  • SET #’S 0-62 AS A POINT. (63 #’s)

  • SET #’S 63-99 AS A MISS. (37 #’s)


Using the random number function
USING THE RANDOM NUMBER FUNCTION scientists to produce the probable results of an experiment or happening.

  • FIND THE RANDOM INTEGER FUNCTION: MATH-PRB #5

  • randInt (min#, max#, amount generated)

  • randInt (0, 99, 2)—(1, 100, 2) will also work.

  • SET UP PARAMETERS AS IN PROB/SIM.

  • KEEP PRESSING ENTER 25 TIMES AND TALLY


Tally time
TALLY TIME scientists to produce the probable results of an experiment or happening.

  • AFTER YOU TALLY YOUR SIMULATIONS:

  • HOW MANY WINS?

  • HOW MANY TIES?

  • HOW MANY LOSSES?


Why have simulations
WHY HAVE SIMULATIONS scientists to produce the probable results of an experiment or happening.

  • COST/DANGER

  • NOT MATHEMATICALLY FEASIBLE

  • NOT PHYSICALLY FEASIBLE


Examples
EXAMPLES scientists to produce the probable results of an experiment or happening.

  • BOMBING OF IRAN (IRAQ EARLIER)

  • DAMAGE DUE TO A POSSIBLE HURRICANE TO THE MIAMI AREA

  • DAMAGE DUE TO A NUCLEAR EXPLOSION ON NEW YORK CITY

  • FINDING THE POSSIBLE PROFIT WHEN A SALES CAMPAIGN IS STARTED


Guided practice
GUIDED PRACTICE scientists to produce the probable results of an experiment or happening.

BUILD SIMULATIONS FOR THE FOLLOWING: RUN 25 SIMULATIONS FOR EACH:

  • THE WEATHERMAN STATES THERE IS A 65% CHANCE OF RAIN NEXT FRIDAY—WILL IT RAIN FOR THE JULY 4 PARADE.

  • THE SCHOOL POPULATION IS AS FOLLOWS: 43% WHITE; 37% HISPANIC; 15% BLACK; AND 5% OTHER. A COMMITTEE IS BEING FORMED –WHAT IS THE RACIAL COMPOSITION OF THE COMMITTEE—IF 12 MEMBERS ARE CHOSEN.

MONTE CARLO SIMULATION


Find the area of the water
FIND THE AREA OF THE WATER scientists to produce the probable results of an experiment or happening.

To further understand Monte Carlo simulation, let us examine a simple problem. Below is a rectangle for which we know the length [10 units] and height [4 units]. It is split into 2 sections which are identified using different colors. What is the area covered by the blue color?

What Is The Area Covered By Blue?

VIEW THE WAVES


CONT. scientists to produce the probable results of an experiment or happening.

Due to the irregular way in which the rectangle is split, this problem is not easily solved using analytical methods. However, we can use Monte Carlo simulation to easily find an approximate answer. The procedure is as follows: 1. randomly select a location within the rectangle2. if it is within the blue area, record this instance a hit3. generate a new location and repeat 10,000 times


Calculation
CALCULATION scientists to produce the probable results of an experiment or happening.

BLUE AREA= # HITS x 40 UNITS

10,000

THIS CAN ALSO BE USED IN MS EXCEL USING CELLS AS POINTS OF CHOOSING BY THE COMPUTER.

THERE ARE MANY DIFFERENT TYPES OF SOFTWARE THAT CAN CALCULATE THIS


Monte carlo practice
MONTE CARLO PRACTICE scientists to produce the probable results of an experiment or happening.

  • DESCRIBE HOW A MONTE CARLO SIMULATION WOULD WORK TO DISCOVER THE PERCENTAGE OF WATER ON THE EARTH’S SURFACE.

  • USING 10,000 TRYS—HOW CAN YOU FIND THE RACIAL PERCENTAGE OF THE POPULATION OF NEW YORK CITY.


How about 3 d
HOW ABOUT 3-D scientists to produce the probable results of an experiment or happening.

  • THE SPREADSHEET, PAPER, AND IDEAS WITH TWO VARIABLES ARE TWO DIMINSIONAL.

  • WHAT ABOUT A 3-D OBJECT?

  • THREE VARIABLES?

  • WHAT ABOUT VOLUME?


Problem
PROBLEM scientists to produce the probable results of an experiment or happening.

  • HOW TO YOU KEEP AN APPLE FRESH ON THE SHELF OF A GROCERY STORE.

  • IF IT SITS TOO LONG IT BECOMES SOFT AND MUSHY—NOT GOOD FOR SALES.

  • IRRADIATION WILL PRESERVE THE APPLE FOR A LONGER SHELF LIFE.
