Ms. Becker records the number of times each student in her class has visited the Science Museum. Based on the responses, she calculates the mean, median, and range of the data set. Ms. Becker's entire class then goes on a field trip to the Science Museum. She updates the data set to include the field trip to the Science Museum. Select words or phrases to complete the statements to describe the impact of the changes. The mean of the data set​ (a)   , the median of the data set​ (b)   , and the range of the data set​ (c)  

• increases

• also increases

• stays the same

• decreases

• also decreases

• also stays the same

Which of the following is true concerning the mean absolute deviation of a set of data?

• It describes the variation of the data values around the median.

• It describes the absolute value of the mean.

• It describes the average distance between each data value and the mean.

• It describes the variation of the data values around the mode.

DATA ANALYSIS : AVERAGE (add up the values, divide by how many!...) : Exact MIDDLE data value (or average of two middle values) : MOST often occurring value (might be more than one mode) : HIGH minus LOW (span) : Lower and Upper is the MIDDLE of the LOWER HALF of the data is the MIDDLE of the LOWER HALF of the data is the MIDDLE of the LOWER HALF of the data
