39. For you to answer
the questions
given, what did
you do first?

40. After observing
the graph, what
is the next thing
that you did?

41. How did you
determine the least
fruit tree available in
the orchard? Students
favored color? Fruit
eaten by the
students? Cars sold?

42. -is the smallest percentage in a
pie graph
-is the shortest bar in a bar graph
-is the least number of
images/pictures in a pictograph
-is the lowest point in a line
graph

43. How did you
determine the mean of
the fruit tree available
in the orchard?
Students favored
color? Fruit eaten by
the students? Cars
sold?

44. 𝑋 =
𝑥
𝑛
where in:
𝑥 − 𝑚𝑒𝑎𝑛

45. How did you
determine the median
of the fruit tree
available in the
orchard? Students
favored color? Fruit
eaten by the students?
Cars sold?

46. Median is the
middle most
frequency in a
data.
