Quizplus · Accepted Answer

Time-series data analysis involves analyzing data over a period of time for the same entity (organization, plant, or activity). This includes using a variety of time periods to measure the dependent variable, such as daily, weekly, monthly or yearly data. Option B is not accurate as only using the highest and lowest observation may not provide enough information about the trend over time. Option C is comparing different entities which is not time series analysis. Option D is comparing cost pools which is not related to time series analysis.
