Question

1. check the box if the statement is an error for random or for systematic. some of the data for the experiment was accidentally deleted from the study. a chemical solution was measured with a cup instead of a beaker with measurements in liters. the temperature is hotter than expected for the experiment. the chemical instrument is known to be faulty and fails to analyze the soil samples accurately.

Explanation:

• Some of the data for the experiment was accidentally deleted from the study: This is a random error. Random errors are unpredictable and can occur due to chance events like accidental data deletion.
• A chemical solution was measured with a cup instead of a beaker with measurements in liters: This is a systematic error. Using an incorrect measuring device (cup instead of a beaker with proper liter - based measurements) leads to a consistent deviation from the true value.
• The temperature is hotter than expected for the experiment: This is a random error. Temperature fluctuations that are not due to a consistent flaw (like a faulty thermometer) but rather due to unforeseen environmental or experimental - setup - related randomness (e.g., a random draft in the room affecting heat transfer) are random errors.
• The chemical instrument is known to be faulty and fails to analyze the soil samples accurately: This is a systematic error. A faulty instrument will give results that are consistently wrong in a particular way (e.g., always over - estimating or under - estimating a certain property of the soil sample).

Answer:

• Some of the data for the experiment was accidentally deleted from the study: Random
• A chemical solution was measured with a cup instead of a beaker with measurements in liters: Systematic
• The temperature is hotter than expected for the experiment: Random
• The chemical instrument is known to be faulty and fails to analyze the soil samples accurately: Systematic
