Happy "Spring"
Well it's freezing cold and we're expecting snow, so happy first day of spring!!!
We have our Statistics Test on Wednesday, March 25th.
We have our Statistics Test on Wednesday, March 25th.
What’s
On the Statistics Test???
1) Be able to identify what is and is not a
statistical question.
2) Be able to answer questions that require you
to read a graph or a chart for information.
«
Bar Graph ~ a bar graph uses vertical or horizontal bars to
display numerical information. The
length of the bar tells you the number it represents.
«
Histogram~ looks like a bar graph, BUT the bars are connected
and a histogram is used when you need to group the data because you have so
many different numbers in your data
«
Box-And-Whisker
Plot ~ shows the range and
distribution of data along a number line.
It is broken into four equal quartiles, highlighting the five number
summary of the data.
«
Line Plot ~ shows the shape of the data. This uses a line and Xs to plot the data.
«
Tally Chart
and Frequency Chart ~ used to collect
and summarize data.
3) Be able to calculate mean, median, mode, and
range.
□
You have a sheet of
cardstock paper with directions on how to calculate each of these.
□
Be able to defend
when to use the mean, median, or mode.
4) Be able to take information and produce a graph.
All graphs must have:
□
a title
□
the horizontal
and vertical axes labeled
□
the graph must
start at 0 where the two axes meet (horizontal and vertical)
□
the scale
(numbers used) needs to be at equal intervals (0, 5, 10, 15…)
□
the scale must be
appropriate for the numbers used
□
the scale numbers
must be on the outside of the graph
□
use lines (“tic
marks”) for the numbers
□
the population
must be stated
For Bar Graphs:
□
bars must not be
connected to the vertical axis ~ there must be a space
□
bars must not be
connected to each other and must be the same width
□
bars must be
equal distance apart ~ the space between the bars must be the same for each bar
For histograms:
Same as a bar graph EXCEPT:
□
the bars are
connected to each other
□
the data is
grouped (Remember our height activity – we grouped students 50-53 inches tall
and so on)
For box-and-whisker plots:
□
used to show the
variation of the data – how it is distributed across a number line
□
the five number
summary (low value, lower quartile, median, upper quartile, and high value) are
plotted above a number line, with a box drawn around the median, through the
lower and upper quartile values.
□
The size of the
quartiles show how the data is distributed.
Small boxes and whiskers indicate that the data is clustered in a small
area. Broad boxes and long whiskers
indicate that the data is spread out (a larger range).
□
The box shows the
middle 50% of the data values.
For a line plot:
□
uses a number
line to represent the data
□
places an X at
each number represented in your data
□
Xs must be the
same size and height
□
has a title and a
label for the horizontal scale
5) Be able
to determine an appropriate scale to be used on a graph.
«
The scale
of a graph is the “ruler” that measures the height of the line or bar.
«
The interval
is the amount of space between the values on the scale.
6) Know the difference between a tally chart and
a frequency chart. Be able to create
each one when given data.
Have a great weekend!

Our Criteria are:
1. There must be a defined population or subject
2. There must be more than two possible answers
3. The data must be able to be represented numerically
