  • This statistical sign "n" means
    number of observations (sample size)
  • This statistical sign "α" means
    level of significance
  • This statistical sign "K" means
    number of samples (each having n elements)
  • This statistical sign "ρ" means
    population correlation coefficient
  • This statistical sign "s" means
    standard deviation (sample)
  • This statistical sign "μ" means
    population mean
  • This statistical sign "σ" means
    standard deviation (population)
  • This statistical sign "v" means
    degrees of freedom
  • This statistical sign "r" means
    sample correlation coefficient
  • This statistical sign "Z" means
    standard normal deviate
  • This statistical sign "¯x" means
    sample mean
  • When calculating for a statistical Type I error researchers generally set α between _____?
    1 and 10%
  • Type II Error
    Not rejecting the Null-Hypothesis (H0) when it is factually false & H1 or the alternate hypothesis is true?
  • This statistical sign "β" means
    Type II Error
  • If we have determined that height and weight are both continuous variables, what test would researchers choose to measure their validity if the variables are also both normally distributed?
    Pearson’s Correlation Coefficient
  • In determining whether height can predict weight you need to decide which of the two is the independent variable and what kind of variable it is?
    Height is the continuous independent variable because you cannot determine height from weight but you could estimate weight given height.
  • Simple linear regression
    This test can help you decide if weight is a good predictor of height and it can produce an equation to predict weight given an individual’s height?
  • CONTINUOUS (SCALE) VARIABLES: Measurements on a proper scale such as age, height etc. INDEPENDENT VARIABLE: The variable we think has an effeculd be influenced by independent variables. t on the dependent variable. DEPENDENT VARIABLE: The variable of interest which co there are various assumptions for
  • Dependent Variable
    Characteristic which varies between independent subjects?
  • Categorical Variables
    With variables such as gender, names, & even hair color that have limited value we would use this classification?
  • Nominal
    Naming variables where one category is no better than another value is called a?
  • Parametric Test
    If we include the assumption that continuous dependent variables are normally distributed. And a histogram of the dependent variable peaks in the middle and is roughly symmetrical about the mean, we can assume the data is normally distributed. How else could we test this assumption?
  • Ordinal
    These variables can have a form of order to their categories, such as,1st, 2nd, 3rd, etc?
  • Gauge the strength of a linear correlation.
    The magnitude of covariance is difficult to interpret so we must use CORREL or PEARSON, the normalized version of COVAR, to?
  • A natural zero point
    Ratio data is interval data with this?
  • Temperature and Year
    2 Examples of interval level data would include, _____&_____, as neither have a 0 point.
