9. What is the order of operations for working through equations? 

3. Distinguish between experimental and correlational designs. 

 6. Distinguish between histograms and bar graphs. When do we use each? 

1.  Distinguish between descriptive and inferential statistics. In your answer, explain what each term means. 

5. When do we use statistics? When do we use parameters? What kind of symbols are used for both? 

Organize the  scores below in a table showing simple frequency, cumulative frequency, and relative frequency.  After doing so, graph the data set choosing an appropriate technique.  Explain why you did not use the other graphical options.  16, 11,  13, 12, 11, 0,  16, 12, 16, 15, 16,  11, 13, 16, 12, 11
