SCIENTIFIC METHOD
STUDY OBJECTIVE D L D PS CONDUCT THE PROCEDURE PA YL SCIENTIFIC METHOD STUDY SL, QS Systematics (WITH STEPS STABLISH) and Counter (WITH DATA PUEDN X be replicated or refute any researcher). SCIENTIFIC METHOD BUT L S JUST ONE COMPONENT DL SCIENTIFIC RESEARCH PROCESS D, Q D 3 LEVELS CONSTA (ARNAUD):
1)Theoretical and conceptual: 1.DEFIDL PROBLEM AND HYPOTHESES 2.DEDUCCION D CONTRASTABLS
2) THEORETICAL-METHODOLOGICAL: 3.STABLECER AN D DATA COLLECTION PROCEDURE D (CHOOSING A RESEARCH DESIGN D)
3) TATISTICS-ANALYTIC: 4.ANALISIS D DATA (D CONTRAST HYPOTHESIS)
INTERPRETING THE RESULTS OBTAINED D (D 5.DISCUSION RESULTS AND CONCLUSIONS BUSQDA D +6. ELABORATION D RESEARCH REPORT D) D LEADS TO NEW LEVEL 1st Home D NEW L PROCESS, creating a cyclic structure.
YOU SHOULD ALWAYS TRY ON A SET OF DATA WITH Q I DESCRIBE THE STUD STAMOS Q iand.
TATISTICS: SCIENCE Q collect, order and analyzed the data a sample from D D TRUE PB YQ, D FROM THAT SHOW WITH L CALCULATION D Probs, S DIRECTS D make inferences about the PB (S D A BRANCH OF THE MATES FUNDAMNTAL PA empirical science). DATA ANALYSIS D L can be done with
LEVELS:
1) A. DESCRIPTION: NATURAL BEHAVIORS SEEN AND MAKES AN TTO D MERAMNT DESCRIPTIVE DATA, identifying GETTING FRECS Y%, CALCULATING AND CORRELACIONS REPRE GRAFICAMNT.
2) A. INFERENTIAL: A sample REPRE D THE HOLD PB A. PA D DESCRIPTIVE RESULTS drawn up for Level D DETER ANY ERRORS OR PROB OF PB.
3) A. EXPERIMENTAL: SE CREAN EXPERIMENTALS CONDICIONS MANIPULATING THE VI AND YOU GETTING THE Valors PA. SE REQIERE ASSIGN 
GROUPS TO COMPARING THE EFFECTS CONDICIONS EXPERIMENTALS. GRADE D DPNDIENDO DL MANIPULACIN D LA VI TNMOS:
– D. OBSERVATIONAL: ABSENCE OR HANDLING minimal DD (naturalistic observation STUDIOS D O CAMPO)
-D.CUASIEXPERIMNTAL: USA GROUPS NO EQIVALENTS
D.SELECTIVOS O-CORRELACIONALS: STUDIO BETWEEN THE RELACIONS VARIABLS by selecting subject based D D D SOME characteristics.
-D.EXPERIEMNTAL: MAXIMUM EXTENT D HANDLING (D LAB EXPERIMENT)

TB can be distinguished:
-TATISTICS THEORETICAL ASPECTS AND REGULATORY Formals
-TATISTICS IMPLEMENTED: APPLICATION TO A PARTICULAR AREA, IN OUR CASE TATISTICS PO APPLIED TO DATA ANALYSIS D.
P D DATA ANALYSIS: TOOLS NEEDED MATODOLOGICA, D CHARACTER STADSITICO, PA RESEARCH IN P.
GENERAL CONCEPTS
PB-SAMPLE, PARAMETER-STADSITICO, feature-MODE
RESEARCH OBJECTIVE D L S characterize the PCA Propertys A PB D: D ALL SET elemntos (ENTIDADS TATISTICS) Q COMPOSING one or more characteristics, PUEDN be finite or infinite.
That characterization is done by Valors Number (%, MEAN …) Q RESUMN THE PB:PARAMETERS (D PROPERTY DESCRIPTION THE PB).
Aunq GENERALMNT, L TOTAL D THE RESEARCHER PAL INACCESSIBLE PB S, X LO Q NO Q USE A SAMPLE: Subset REPRE elemét D AN D THE PB, S FUNDAMNTAL PA Q SEA REPREY TATISTICS IT HAS THE SAMPLING L,, Q PA STUDIA METHODS Sample Extraction REPRE.
That sample L researchers to calculate their Valors RESUMN: STATISTICS (SAMPLE PROPERTY DESCRIPTION D), and thereby infer RESLUTADOS Propertys D DETER THE PB.
LOS UNICOS aunq Valors PARAMETROSTIEN are unknown, is symbolized by Greek letters (?, ?, ?). Puen THE STATISTICS HAVE SHOWN MANY Valors is taken, is symbolized by LETRAS LATINAS (

).
THE UNS PB Propertys D STAN PRESENTS IN ALL FORMING Is DQ, aunq no to the same degree (eg: MARITAL STATUS: Widowed, divorced, single ..)
– Feature: Property Q Is COMPARTN THE ONE PB
– MODE: D EACH AS REPRESENT THE VARIANTS a feature.
IN THE STUDIOS P CARACERISTICAS AS REFERRED TO PERSONALITY, MEMORY .. Q ADOPT MODALIDADS, Q PA STADISTICAMNT BE TREATED EXPRESDAS D HAN D STAR numerically.
MEASUREMENT AND SCALES MEASURE D
MEASUREMENT: DN ALLOCATION PROCESS D objects or features you ACCORDING TO DETER RULES. SUPPOSED TO MEASURE D ratio L WORLD IDEL Nos AND OBJECTS L REAL D, D MODE RELACINS Q Q GIVEN THE L WORLD IN THE RELACIONS EXACTMANT number preserves Q SEEN in the empirical world, and would only be VALID MAY AQLLAS RELACIONS number Q SER VERIFICABLS EMPIRICAMNT.
PA WITH THAT WE SCALAS D ACTION: PROCEDURE RELATED XLQ biunique THE FORM D A property with MODALIDADS D D N A SET os, PA each mode. 4 TYPES D SCALES (Stevens):
1) CALL: YES 2 Observacions belongs to the same Amodal were assigned L SAME NO, AND IF YOU BELONG TO MODALIDADS, Nos.. The numbers assigned TIEN Q = DAD OR REFLECT THE Q MODALIDADS BETWEEN DAD have the characteristic.
EJ: sex (male, female), personality (introvert, extrovert ..) TRANSFORMATION ELIGIBLE: CUALESQIERAQ Nos. L PRESERVE ORDER THEDAD = O DAD EMPIRICAMNT OBSERVED BETWEEN MODE.
2) ORDINAL: Puen INDICATING OBJECTS TO DETER CHARACTERISTIC> O <DEGREE SOME OTHER Q, D Q MODE OFDBN ASSIGNED Nos. reflect this magnitude. EJ: NOTE :0-SUSPENSE, 1-APPROVED ,2-NOTABLE ,3-ON, 4-D HONOR Transformation ELIGIBLE ENROLLMENT: PRESERVE CUALESQIERA Nos. Q D L ORDER MAGNITUDE, increasing or decreasing OBJECTS IN Q have the characteristic.
