Ascientist counts the number of bacteria colonies growing in each of six lab dishes.

bacteria colonier per dish
letter = dish label
number = amount of colonies
a -16
b - 13
c - 25
d - 3
e - 13
f - 13
why is 13 considered to be the mode of this data set?

a. it is the most likely number of colonies that would grow in a dish.
b. it is in the center of the range of the number of colonies.
c. it is the data value that appears the most often in the set.
d. it is the ideal number of colonies that the scientist should grow.

Hi!

The correct answer is: C. It is the data value that appears the most often in the set.

The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are

A - 16 , C - 25 , D - 3

While 13 appears three times with the dishes labelled

B , E and F

So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
