Does time series data contain values of a characteristic of a subject over time?
Time series data contain values of a characteristic of a subject over time. A qualitative variable assumes meaningful numerical values. Both discrete and continuous variables may assume an uncountable number of values. A continuous variable assumes any value from an interval (or collection of intervals).
What type of statistics is often used to describe the average value of a variable in a population?
Descriptive statistics are broken down into measures of central tendency and measures of variability (spread). Measures of central tendency include the mean, median, and mode, while measures of variability include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.
Which of the following are examples of the interval scale of measurement?
An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include: temperature (Farenheit), temperature (Celcius), pH, SAT score (200-800), credit score (300-850).
Which of the following is the best example of a continuous ratio variable?
Examples of continuous variables are blood pressure, height, weight, income, and age. Rank-ordering data simply puts the data on an ordinal scale. Ordinal measurements describe order, but not relative size or degree of difference between the items measured.
Is ratio data qualitative or quantitative?
Unlike nominal- and ordinal-level data, which are qualitative in nature, interval- and ratio-level data are quantitative. Examples of interval level data include temperature and year. Examples of ratio level data include distance and area (e.g., acreage).
Is income a data ratio?
