ACCURATE ANSWERS
NOIR - ACCURATE ANSWERS✔✔ Data types: nominal, ordinal,
interval, ratio
Nominal - ACCURATE ANSWERS✔✔ Yes or No variables or sex,
mortality, dz presence, race, marital status
Ordinal - ACCURATE ANSWERS✔✔ Ranked in order but no
magnitude of ranks. Ex: NYHA, scale
*means and SD should not be reported
Interval - ACCURATE ANSWERS✔✔ Data ranked in order. Zero is
arbitrary. Points can pass zero. Ex: Fahrenheit temperature
Ratio - ACCURATE ANSWERS✔✔ Measurables and continuous. The
values don't cross zero. Ex: HR, BP, time, distance
Visual methods of describing data (3) - ACCURATE ANSWERS✔✔
Frequency distribution, histogram, scatterplot
, Measures of central tendency - ACCURATE ANSWERS✔✔ Mean,
median, mode
Mean - ACCURATE ANSWERS✔✔ Generally used for continuous and
normally distributed data
Median - ACCURATE ANSWERS✔✔ Midpoint of values when placed
in order from highest to lowest
*ordinal or continuous data
Mode - ACCURATE ANSWERS✔✔ Most common value
* used for nominal, ordinal or continuous
*does not help describe meaningful distributions with a large range of
values each occurring infrequent
2 types of discrete variables - ACCURATE ANSWERS✔✔ Nominal
and ordinal
Nominal data - ACCURATE ANSWERS✔✔ Unordered data. Ex-sex,
mortality, disease presence, race, marital status
Ordinal data - ACCURATE ANSWERS✔✔ Ranked in "order" but no
consistent level of magnitude of difference between ranks. 1 and 2 in the
