What are the different types of measurements? - correct answer✔✔1. Nominal
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
2. Ordinal |||\\\
3. Interval |||\\\
4. Ratio |||\\\
What is nominal measurement? - correct answer✔✔This is the lowest level of measurement
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
|||\\\ - It uses numbers simply to categorize attributes
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- Don't have quan meaning and can't be treated mathematically
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Ex = gender, ethnicity, etc. |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
|||\\\ - Items are put into categories, but they cannot be ranked - this is just data for what it is
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
ex:
1 = anglo |||\\\ |||\\\
2 = african american
|||\\\ |||\\\ |||\\\
3 = hispanic |||\\\ |||\\\
4 = asian |||\\\ |||\\\
5 = other |||\\\ |||\\\
What is ordinal measurement? - correct answer✔✔Ranks people on an attribute
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- typically organized in categories and can be computed or ranked highest to lowest
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- Usually data is exclusive and has unequal intervals
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
,Ex = mild, moderate, and severe pain
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
ex = lower income, middle income, and upper income
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What is interval measurement? - correct answer✔✔Ranks people on an attribute and specifies
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
the distance between them |||\\\ |||\\\ |||\\\
|||\\\ - This is usually equal numerical distances between intervals
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- Typically an interval value and they lack a zero point
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
Ex temperature |||\\\
What is ratio measurement? - correct answer✔✔This is the highest level of measurement
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- Ratio scales (unlock interval scales) have a meaningful zero and provide information about the
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
absolute magnitude of the attribute |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- This is typically ordered at equally spaced intervals
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- This has a continuum value and has an absolute zero
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- ex a 200 lb person is twice as heavy as a 100 lb person
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- This yields more information and is more receptive to power analysis
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What type of measurement do we need to use with Pearson's R? - correct answer✔✔interval
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
or ratio level variables |||\\\ |||\\\ |||\\\
What are indirect measurements? - correct answer✔✔surveys & comparative psychology
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What is descriptive data? - correct answer✔✔used to describe & synthesize data
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
• parameters: descriptor for a population
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\
• statistics: descriptive index from a sample
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
• descriptive statistics address one variable
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\
, • also referred to univariate
|||\\\ |||\\\ |||\\\ |||\\\
What is a positive skew? - correct answer✔✔Long tail points to the right
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- this is asymmetric aka the peak isn't in the middle
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What are central tendency measurements? - correct answer✔✔Common form of statistical
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
analysis used to described what is typical or the midpoint of the data |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
1. Mode |||\\\
2. Median |||\\\
3. Mean |||\\\
What is the mode? - correct answer✔✔The number that occurs most frequently
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- Used to identify popular data
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- Used with nominal data
|||\\\ |||\\\ |||\\\ |||\\\
What is the median? - correct answer✔✔The point that divides the scores in half
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
|||\\\ -Used with ordinal data |||\\\ |||\\\ |||\\\ |||\\\
- typically not affected by extreme scores
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
- typical preference for a skewed score
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What is the mean? - correct answer✔✔The sum of all the values divided by the number of
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
participants
|||\\\ - used with interval or nominal data
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\
What are outliers? - correct answer✔✔People off the scales
