The first quartile of a data set is 2.5. Which statement about the data values is true? One fourth of the values are less than or equal to 2.5, and three fourths of the values are above 2.5. Half of the values are less than or equal to 2.5, and half of the values are more than 2.5.Three fourths of the values are less than or equal to 2.5, and one fourth of the values are above 2.5. One fourth of the values are less than or equal to 2.5, and half of the values are above 2.5.
Accepted Solution
A:
the first quartile represents 25%....or 1/4 of the data 2nd quartile represents 50%..or 2/4 3rd quartile represents 75%...or 3/4
so if the 1st quartile is 2.5.....1/4 of the values are less then or equal to 2.5, and 3/4 of the values are above 2.5
