    The ______ describes how scattered or spread out the scores are from the mean value of the random variable

    Variance and Standart Deviation

  • 10

    The Standard Deviation is denoted by ___ and is the square root of the variance

    ó

  • 11

    Also known as Gaussian distribution, is an arrangement of a data set in which values cluster in the middle of the range and the rest decreases symmetrically towards either extreme

    Normal Distribution

  • 12

    The Normal Curve has

    A single peak

  • 13

    Discrete Data has the following qualities:

    Limited and Countable

  • 14

    It is a symmetric distribution the is speaked at the center, and Approaches the horizontal axis the farther from the center of the distribution the t value.

    Normal Random Distribution

  • 15

    A branch of mathematics that deals with the occurrence of a random event

    Probability

  • 16

    It is the study of the collection, analysis, interpretation, presentation, and organization of data.

    Statistics

  • 17

    A type of statistics that is A set of brief descriptive coefficients that summarize a given data set representative of an entire or sample population.

    Descriptive Statistics

  • 18

    Uses statistic tests, either to test for significant relationships among variables or to find statistical support for hypothesis.

    Inferential Analysis

  • 19

    Is an important factor in determining the representativeness of the sample population and the degree to which the change affects the findings.

    Level of Significance

  • 20

    It's defined as a wise guess that is formulated and temporarily adopted to explain the observed facts covered by the study.

  • 23

    UNIVERSE

    Collection or set of units from whom we got the whole data.

  • 24

    POPULATION

    Set of all possible values of a variable

  • 25

    CONTINUES RANDOM VARIABLE

    THE DISTANCE BETWEEN TWO THINGS

  • 28

    CHARACTERISTICS OF NORMAL DISTRIBUTION

    The total area under the curve is 1.00 and since the curve is symmetric about x = μ. It follows that the area on either side of the vertical line is 0.50. This area represents the total number of cases (N).

    THE Z-TABLE

    also known as the table of probabilities. It was created to summarize the approximate area under the standard normal curve and to further simplify the process.

  • 33

    a measure used in statistics indicating the value below which a given percentage of observations fall.

    PERCENTILE

  • 34

    Z-TEST

    It is appropriate to use when the variance came from the sample data.
