As these notes are not the most encouraging, and you want to see what happened with the exam, prepare ONE SINGLE TABLE of frequency distribution using the two notes of the groups, to get a good representation the intervals that please are eight. Please look up the class intervals and range. The data should go from the highest to the lowest score. GOOD LUCK. You must prepare the following graphs, warhead. They must give the interpretation to these results.

Rubric:

40 pts. The Table is complete with all its parts, NO column is missing from it, all the numbers are correct. Either pts the table is missing columns or there is an error in the table which makes the rest of the table incorrect.

10 Pts. Give a correct interpretation to the results. 0 pts, your interpretation of the results is incorrect.

5 pts. Makes the graph correctly and includes all the data referring to it (example: axes, title, etc.) 0 pts. He makes the graph but it is wrong.
