Which practices help make a table of repeated measurements clear and useful? Select all that apply.

  1. A

    Give the table a specific title and headings that include units.

  2. B

    Replace all individual trial results with only the mean.

  3. C

    Keep the original measurements so they can be checked later.

  4. D

    Record measurements to a consistent level of precision.

One trial in an investigation gives a result very different from the other trials. What is the best next step?

  1. A

    Delete the result because it does not fit the pattern.

  2. B

    Change the result so it is closer to the other trials.

  3. C

    Keep the result and examine the trial and measurement conditions for a possible explanation.

  4. D

    Ignore all the other trials and base the conclusion on this result alone.

A seedling investigation found greater mean height at higher light levels. Which considerations limit how confidently the results support the conclusion that light caused the height differences? Select all that apply.

  1. A

    Water, temperature, or soil could have affected growth if those factors were not controlled.

  2. B

    The observed relationship between light exposure and height proves that light caused the height difference.

  3. C

    Limited measurement precision could affect how confidently heights can be compared.

  4. D

    Too few trials could make it harder to judge whether a pattern is consistent.

Which statement is a direct observation from the seedling results rather than an explanation of what caused them?

  1. A

    The mean seedling heights were 4 cm, 7 cm, and 10 cm at 0, 4, and 8 hours of light, respectively.

  2. B

    More light caused the seedlings to grow taller.

  3. C

    The seedlings grew taller because their soil was better.

  4. D

    The trial results prove that light is the only factor affecting seedling height.

A student is preparing a table of measurements from an investigation. Which approach would make the table clearest for comparing results?

  1. A

    Remove units from the headings so the table has less text.

  2. B

    Give the table a specific title, label its headings with units, and record measurements to consistent precision.

  3. C

    Replace all individual measurements with a single summary value.

  4. D

    Use different precision for each measurement to show more detail.

A student reports the mean height for each light level but also includes every trial result. What important information do the individual results provide?

  1. A

    It guarantees that every trial produced the same result.

  2. B

    It proves which variable caused any differences.

  3. C

    It shows how much the repeated measurements varied.

  4. D

    It removes the need to label the measurements with units.

In the seedling results, mean heights were 4 cm at 0 hours of light, 7 cm at 4 hours, and 10 cm at 8 hours per day. Which pattern do these results show?

  1. A

    Mean height decreased as daily light exposure increased.

  2. B

    Mean height increased at each higher level of daily light exposure shown.

  3. C

    Mean height stayed the same at all three light levels.

  4. D

    The data show that all seedlings had the same height.
