Thank you for the opportunity to help you with your question!

1. Imprecise means that the measurements are not close to each other. Inaccurate data would mean that the measurements are not close to 3.3cm.

Example: 1cm, 5cm, 3cm, 9cm, 15cm

2. Precise means the data are close to each other, but inaccurate means they are not close to the actual value.

Example: 5cm, 5.2cm, 4.8cm, 5.4cm, 5.1cm

3. Measurements are close to each other and close to actual value.

Example: 3.3cm, 3.1cm, 3.4cm, 3.4cm, 3.2cm

Oh thank you very much
