Criteria

Levels of Achievement

Content 70%

(28 points)

Advanced 90-100% (A)

Proficient 70-89% (B-C)

Developing 1-69% (< D)

Not present

Frequency Distribution (#1 & #2)

(16 points)

14.4 to 16.0 points

Correct class width, starting value, all classes the same width, no missing classes, no counting errors. All parts (frequency, midpoint, relative frequency, cumulative frequency) are present and accurate

11.2 to 14.3 points

Small errors noted with up to three of the following (2 pts each): class width, starting value, not all classes same width, missing classes, midpoint, relative frequency, cumulative frequency

1 to 11.1 points

More than three errors noted of the following (2 pts each): class width, starting value, not all classes same width, missing classes, midpoint, relative frequency, cumulative frequency

0 points

Histogram (#3)

(4 points)

3.6 to 4.0 points

Histogram correctly made with vertical bars touching each other and heights reflect the frequency distribution.

2.8 to 3.5 points

Histogram bars do not touch or do not exactly match the frequency distribution (but it is close)

1 to 2.7 points

Histogram does not reflect frequency distribution or is not a histogram at all.

0 points

Ogive (#4) (4 points)

3.6 to 4.0 points

Ogive correctly shows cumulative frequencies. The graph touches the x-axis on the left side of the data

2.8 to 3.5 points

Ogive shows cumulative frequencies, but the graph does not touch the x-axis the left of the data.

1 to 2.7 points

Ogive is incorrect shape

0 points

Temperatures in error and confidence in data (#5)

(4 points)

3.6 to 4.0 points

Correctly identify states with errors and address how this affects the confidence in the validity of the data

2.8 to 3.5 points

Incorrectly identifies states with errors but correctly identifies how this impacts the confidence in the validity of the data

1 to 2.7 points

Incorrectly concludes how any errors could impact the confidence in the validity of the data

0 points

Structure 30%

(12 points)

Advanced 90-100% (A)

Proficient 70-89% (B-C)

Developing 1-69% (< D)

Not present

Histogram (#3) (4 points)

3.6 to 4.0 points

Both the x and y axes are labeled in a way that describes what the histogram represents. There is also a title present that connects back to the data set.

2.8 to 3.5 points

Either the axes are not labeled clearly or the histogram has a title such as “histogram” which does not connect back to the data set

1 to 2.7 points

Both that axes and the title are incomplete or missing.

0 points

Ogive (#4)

(4 points)

3.6 to 4.0 points

Both the x and y axes are labeled in a way that describes what the Ogive represents. There is also a title present that connects back to the data set.

2.8 to 3.5 points

Either the axes are not labeled clearly or the polygon has a title such as “Ogive” which does not connect back to the data set

1 to 2.7 points

Both the axes and the title are incomplete or missing.

0 points

Grammar (#5)

(4 points)

3.6 to 4.0 points

Grammar is perfect. Questions are answered in complete sentences.

2.8 to 3.5 points

Minor grammar errors may be noted, but they do not interfere with the readability of the responses. Answers are in complete sentences.

1 to 2.7 points

Answers are either not in complete sentences or are full of grammar errors that impact the readability of the responses.
