Epidemiology Chapter 2

  1. Enumeration and Tabulation
    Listing all the data and creating a frequency table.
  2. Histogram
    A bar chart used for continuous variables.
  3. Line Graph
    Used to display trends.
  4. Pie Chart
    A circle that shows the proportion of cases according to several categories.
  5. Percentage
    A proportion multiplied by 100.
  6. Proportion
    A type of ratio in which the numberator is part of the denominator.
  7. Ratio
    The value obtained by dividing one quanitity by another.
  8. Rate
    Also a type of ratio, denominator involves a measure of time.
  9. Count
    Total number of cases of a disease or other health phenomenon being studied.
  10. Period Prevalence
    All cases of a disease within a period of time. When expressed as a proportion, refers to the number of cases of illness during a time period divided by the average size of the population.
  11. Point Prevalence
    Number of caes of illness in a group or population at a point in time divided by the total number of persons in that group or population.
  12. Prevalence
    Number of existing cases of a disease or health condition in a population at some designated time.
  13. Incidence
    the occurrence of new disease or mortality within a defined period of observation in a specified population.
  14. Incidence Rate
    Number of new cases of a disease, or other condition, in a population divided by the total number of population at risk over a time period, times a multiplier.
  15. Population at Risk
    Those members of the population who are capable of developing a disease or condition.
  16. Reference Population
    Group from which cases of a disease have been taken; also refers to the group to which the results of a study may be generalized.
  17. Case Fatality Rate
    Number of deats caused by a disease among those wh ohave the disease during a time period.
  18. Crude Rate
    A summary rate based on the actual number of events in a population over given time period.
  19. Death rate
    Approximates the proportion of a dpopulation that dies during a time period of interest.
  20. Specific rate
    Statistic referring to a particular subgroup of the population defined in terms of age, race, or sex; also may refere to the entire population but is specific to some single cause of death or illness.
  21. Adjusted rate
    Rate of morbidity or mortality in a population in which statistical procedures have been applied to permit fair comparisons across populations by removing the effect of differences in the composition of various populations.
  22. Cause Specific Rate
    A measure that refers to mortality divided by the population size at the midpoint of a time period times a multiplier.
  23. Age-Specific rate
    the number of cases per age group of a population during a specified time period
  24. Sex-Specific Rate
    The frequency of a disease in a gender group divided by the total numer of persons in that gender group during a time period times a multiplier.
