    From the time series plot above, which options below best describe the features of the plot? - ProProfs

    From the time series plot above, which options below best describe the features of the plot?

    • Increasing Trend

    • Decreasing Trend

    • Seasonal Variation

    • Discontinuous Structural Change

    • Random Variation

    • Outliers

    Correct Answer(s)
    A. Decreasing Trend
    A. Seasonal Variation
    A. Random Variation
    Explanation
    The time series plot shows a clear decreasing trend, as the data points consistently decrease over time. Additionally, there is evidence of seasonal variation, as there are regular patterns or cycles in the data. There is also random variation present, as the data points do not follow a strict pattern and fluctuate randomly. However, there is no evidence of a discontinuous structural change or outliers in the plot.
