From the time series plot above, which options below best describe the features of the plot?
- A.
Increasing Trend
- B.
Decreasing Trend
- C.
Seasonal Variation
- D.
Random\Irregular Variation
- E.
Outliers
- F.
Structural Change
Correct Answer(s)
A. Increasing Trend
C. Seasonal Variation
D. Random\Irregular VariationExplanation
The time series plot shows a consistent upward movement over time, indicating an increasing trend. Additionally, there are repeated patterns or cycles in the data, suggesting the presence of seasonal variation. Furthermore, there are fluctuations that do not follow a specific pattern, indicating random or irregular variation. Therefore, the plot exhibits an increasing trend, seasonal variation, and random/irregular variation.Rate this question:

Structural Change
Correct Answer(s)
A. Increasing Trend
C. Seasonal Variation
D. Random\Irregular VariationExplanation
The time series plot above shows an increasing trend, as the values are generally rising over time. Additionally, there is evidence of seasonal variation, as there are regular patterns or fluctuations that occur at certain intervals. There is also random or irregular variation present, as there are fluctuations that are not explained by the trend or seasonality. However, it is not possible to determine if there are outliers or structural changes based on the given information.Rate this question:

Structural Change
Correct Answer(s)
A. Increasing Trend
C. Seasonal Variation
D. Random\Irregular VariationExplanation
The time series plot shows an upward trend, indicating an increasing trend over time. Additionally, there are noticeable fluctuations that occur at regular intervals, suggesting the presence of seasonal variation. Furthermore, there are random or irregular variations in the data points, indicating some level of unpredictability. However, there is no indication of a decreasing trend, outliers, or structural change in the plot.Rate this question:

Structural Change
Correct Answer(s)
B. Decreasing Trend
C. Seasonal Variation
D. Random\Irregular VariationExplanation
The time series plot above shows a decreasing trend as the values gradually decrease over time. Additionally, there is evidence of seasonal variation as the plot exhibits regular patterns or fluctuations that occur at consistent intervals. Furthermore, there are random or irregular variations observed in the plot, indicating that there are unpredictable fluctuations that do not follow any specific pattern. However, the presence of outliers or structural changes cannot be determined based on the given information.Rate this question:

Discontinuous Structural Change
- E.
Random Variation
- F.
Outliers
Correct Answer(s)
B. Decreasing Trend
C. Seasonal Variation
E. Random VariationExplanation
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.Rate this question:

Correct Answer(s)
A. Increasing Trend
C. Seasonal Variation
E. Random VariationExplanation
The time series plot shows an upward trend, indicating an increasing trend over time. Additionally, there is evidence of seasonal variation, as there are regular patterns or cycles observed. The plot also exhibits random variation, with fluctuations that do not follow a specific pattern. However, there is no indication of a decreasing trend or discontinuous structural change. Outliers, which are extreme values that deviate significantly from the overall pattern, are not evident in the plot.Rate this question:
