2.7 Data and Measures of Central Tendency Integ. Math

Making Frequency Tables 1.Juan recorded the batting averages of 2 baseball players each of the ten teams in the league. Construct a frequency table of the data:.243,.281,.255,.296,.278,.248,.267,.303,.254,.292,.304,.269,.253,.241,.249,.281,.277,.295,.244,.294,.266,.25,.270,.268,.261,.302,.276,.265

Make a frequency table. Listed below is the average amount spent by 2 individuals per trip to Casey’s use the data: 2, 5, 3, 4, 6, 5, 2, 1.24, 5.32, 5, 6, 4, 7, 12, 4, 3, 2, 9, 7, 2.54, 13, 2.85, 4, 3, 7, 5, 4, 5

Measures of Central Tendency Mean Median Mode

The SAT mathematics scores for 8 high school students are listed below: 539, 541, 576, 505, 548, 576, 565, 558 Find the mean Find the median Find the mode Which measure of central tendency is the best indicator of the typical SAT mathematics score for these students?

A photographer sold photos to a magazine for the following: 150, 175, 350, 120, and 550. Find the mean Find the median Find the mode Which measure best shows the average purchase price for one of his pictures?
