Data on 30 year mortgage interest rates from 1960 to 2001 is called

Cross-sectional data or Qualitative data or Discrete data or Time series data?

ANSWER: Here the data of mortgage interest is selected for 30 years, so the data based on timely changes in the interest rates is available. therefore this data is called as time series data. The values of Interest rates are numeric values therefore this is not qualitative data but quantitative data. The interest rate may change with very small to very large any value, no restriction can be imposed of having isolated values, therefore this data is continuous data. The data is considered over a long period of time and for only one variable and one category mortgage, so this is not cross sectional data. Thus the data would be called Time Series Data.
