PARA #139 MATH - BASIC DATA ANALYSIS QUESTIONS
WITH ACCURATE ANSWERS
statistics Accurate Answer - An area of mathematics that deals with the
relationships among groups of data.
range Accurate Answer - The difference between the greatest number
and the least number in a set of data.
mean Accurate Answer - The average of a set of data. It can be found by
adding all the numbers in a set of data, and then dividing the sum by the total
number of numbers in the set.
median Accurate Answer - The number that falls exactly in the middle
of a set of data.
How can you find the median with an even group of numbers?
Accurate Answer - If there is an even number of numbers, then there is no
single middle value; the median is then usually defined to be the mean of the
two middle numbers: so the median of 3, 5, 7, 9 is(5+7)2=6.
mode Accurate Answer - The number that occurs most often in a set of
data.
graph Accurate Answer - A diagram that shows relationships among
sets of numbers.
bar graph Accurate Answer - A type of graph that has vertical or
horizontal bars that may represent numbers or percentages.
circle graph (pie chart) Accurate Answer - A type of graph that shows
the whole and the percentages or fractions into which the whole has been
divided.
reading a graph Accurate Answer - The title of the graph explains what
information is given in the graph.
✓ The headings of the different sections of the graph give specific information
about what is represented in the graph.
