Question

i need to learn how to make a histogram in logger pro?

Anyone here to help me?

Answer 1

1. Double-click on icon for "Logger Pro" (R), located on PC desktop
[Insert icon graphic: C:\Program Files\Vernier Software\Logger Pro 3\Help\
GAicon.jpg <-- 2.2 KB 75x53x24b]

2. Close "Tip of the Day" window; DO NOT uncheck "Show Tips on Startup"

[Note: The following step may be unnecessary when using more recent
versions of "Logger Pro" (R) (later than Ver. 3.2).]
3. In the "Connect to LabPro" window, click radio button for "Continue
Without Interface"; click "OK"

4. By default, Logger Pro displays two "objects": a data set; and a graph.
The data set is named, "Data Set"; the graph is untitled. The data set has
two columns labeled, "X" & "Y": "X" values are plotted on the horizontal
axis of the graph; "Y" values are plotted on the vertical axis. Retitle
the "Data Set" and "X" & "Y" columns by double-clicking on their labels:

Double-click "Data Set" - "Data Set Options" window pops-up.
"Name:" [Enter appropriate information.]
"Comments:" [Enter appropriate information.]
Click button labeled, "OK"

[Note: By convention, the independent variable (IV) is plotted along the
x-axis.]
Double-click "X" - "Column Options" window pops-up.
Click tab labeled, "Column Definition"
"Labels and Units:" [Enter the following info...]

"Name:" [Enter appropriate information.]
"Short Name:" [Enter appropriate information.]
"Units:" [Enter appropriate information.]
"Insert Symbol:" [If necessary, then select appropriate symbol.]
Click button labeled, "Done"

[Note: By convention, the dependent variable (DV) is plotted along the
y-axis.]
Double-click "Y" - "Column Options" window pops-up." [Repeat process used
to label column "X".]

5. Perform mathematical calculations using columns of data:

Menu bar/Data/New Calculated Column...
"Label and Units:" [Enter appropriate information.]
"Equation:" (see several practical examples below...)

Example A) Calculated Density (CalcDen, g/cc)
"Variables (Columns):" Select first variable, e.g., Y; enter math
operation in equation, e.g., / (division); select second variable, e.g.,
X; click "Done"

Example B) Mean Density (MeanDen, g/cc)
Click button labeled, "Functions >"; select "statistics/mean"; select
variable, e.g., Density; click "Done"

[Note: The following step is optional.]
6. Right-click on graph; select "Delete"

7. Display histogram:

Menu bar/Insert/Additional Graphs/Histogram
Ctrl-click-drag graph to move graph; resize as appropriate
Double-click inside histogram; "Histogram Options" window pops-up
Click tab labeled, Bin and Frequency Options"; select "Columns" to
display, e.g., (calculated) Density; under "Bin-Axis" enter the "Bin
Size:", e.g., 0.1, and/or "Bin Start:"; click "Done"
***Note: Need to add guidance re: selecting appropriate values for "Bin
Size" and "Bin Start"; default values are "1" and "0.5" respectively.
For a histogram showing frequency vs. calculated density, a bin size of
0.1 is suggested.***

***Note: Changes to the data set are automatically reflected in calculated
column(s), graph, and histogram.***

8. From the menu bar, select "File/Printing Options..." - "Printing
Options" window pops-up. [Enter the following info...]

Check box for "Print Footer"
"Name:" [Enter last names only, separated by commas.]
"Comment:" [Enter Period 1, 2, or 3, as appropriate.]
Check box for "Date"; uncheck boxes for "Page Title" and "Page Number"
DO NOT uncheck "Always Show This Dialog Before Printing"
Click button labeled, "OK"

9. Double-check the histogram to be sure it features ALL of the elements
of a good graph:

- a labeled data table, including units
- a clear, concise title that tells what the histogram shows
- both axes labeled, including units [A simple histogram shows how the
frequency of the data (y-axis) is related to one variable, such as
density (x-axis).]
- the histogram fills the window (virtual graph paper)
- histogram features a legend (a.k.a., a "key") -- a "must have" for
histograms showing the frequency of two- or more variables

10. Print hardcopy [Punch holes in paper(s) for secure storage in
three-ring binder. Circle your name (see page footer).]

Option A [Prints both data table and graph/histogram.]
From the menu bar, select "File/Print..." - "Printing Options" window
pops-up [Double-check settings, Step #8.]
Click "OK"
"Print" window pops-up; select "Printer - Name:" [if necessary] and
"Copies - Number of copies:" [Print one copy for each student in group.]

Option B [Prints data table only.]
From the menu bar, select "File/Print Data Table..." - "Printing Options"
window pops-up [Double-check settings, Step #8.]
Click "OK"
"Print" window pops-up; select "Printer - Name:" [if necessary] and
"Copies - Number of copies:" [Print one copy for each student in group.]

Option C [Prints graph/histogram only.]
From the menu bar, select "File/Print Graph..." - "Printing Options"
window pops-up [Double-check settings, Step #8.]
Click "OK"
"Print" window pops-up; select "Printer - Name:" [if necessary] and
"Copies - Number of copies:" [Print one copy for each student in group.]
