Question 3: In environmental data analysis, what is the benefit of applying principal component analysis (PCA)?

Which action should you take?

Choose only one option

It removes noise from high-frequency environmental data

It helps in real-time decision-making without historical data

It increases the complexity of data sets by adding new variables

It reduces the dimensionality of the dataset while preserving most of the variance

Question 4: What is the primary advantage of using time series analysis in environmental data analysis?

Which action should you take?

Choose only one option

It focuses only on spatial relationships in the data

It simplifies the complexity of environmental variables

It helps detect patterns and trends over time, aiding in forecasting

Which action should you take?

Choose only one option

The distribution of pollution sources

Seasonal trends in temperature fluctuations

Spatial distribution of water quality across regions

Geographical changes in biodiversity

Question 6: How do you ensure that environmental data collected through citizen science programs is reliable?

Which action should you take?

Choose only one option

By excluding all citizen-collected data due to potential errors

By designing clear protocols, providing training, and cross-validating citizen-collected data with professional sources

By assuming that citizen-collected data is inherently accurate

By collecting only data from experts and ignoring citizen reports
