In a practical report, where should the hypothesis be stated?

• In the introduction

• In the conclusion

• In the results section

• In the discussion

What is the purpose of using significant figures in measurements?

• To increase the accuracy of a measurement

• To indicate the precision of a measurement

• To simplify calculations

• To convert units

Which of the following is an independent variable in an experiment?

• The time taken for a reaction to occur

• The concentration of a solution

• The mass of the product formed

• The volume of gas produced

How can the reliability of data be improved in an experiment?

• By using more precise instruments

• By repeating the experiment multiple times

• By increasing the sample size

• By using a control group

What is the role of the discussion section in a practical report?

• To present the raw data collected

• To interpret the results and relate them to the hypothesis

• To list the materials and methods used

• To summarise the experiment

Which of the following statements is true about precision in measurements?

• Precision refers to how close a measurement is to the true value

• Precision is the same as accuracy

• Precision refers to the consistency of repeated measurements

• Precision is not important in scientific experiments
