Front

What is average light intensity?

Back

Average light intensity refers to the mean amount of light received over a specific period, often measured in lumens or foot-candles.

Front

How do you determine the lowest value in a data set?

Back

To find the lowest value, compare all values in the data set and identify the smallest one.

Front

What is the significance of air temperature in scientific studies?

Back

Air temperature can affect various biological and chemical processes, influencing the outcomes of experiments.

Front

What does fluctuation in data indicate?

Back

Fluctuation indicates variability or changes in data points over time, which can suggest trends or patterns.

Front

How do you calculate the change in temperature over time?

Back

Change in temperature is calculated by subtracting the initial temperature from the final temperature.

Front

What is the purpose of using graphs in scientific studies?

Back

Graphs visually represent data, making it easier to identify trends, patterns, and relationships.

Front

What does CO percentage in exhaust indicate?

Back

The CO percentage in exhaust indicates the level of carbon monoxide produced, which can reflect combustion efficiency.

Front

How can you identify the section with the largest fluctuation in data?

Back

Compare the range of values (highest - lowest) for each section to determine which has the greatest difference.

Front

What is the importance of specific time markers in data analysis?

Back

Specific time markers help pinpoint when certain events or changes occur, aiding in understanding trends.

Front

What does a positive change in temperature indicate?

Back

A positive change in temperature indicates an increase in temperature from the initial to the final measurement.
