Creating (ab) Single Subject Design Graphs

CREATING (AB) SINGLESUBJECT DESIGN GRAPHS IN MICROSOFT EXCEL 2003 Lets try to graph this data Date Baseline Data Date NCR (intervention) 11/10 2 11/15 3 11/11 3 11/16 3 11/12 3 11/17 2 11/13 1 11/18 1 11/14 2 11/19 2 11/20 0 11/21 0 11/22 0 1 Step 1: Set up the Variables AB Design Use the top cells to Label the variables that will be displayed on X and Y axis of the graph Step 1: Set up the Variables X-Axis for AB design • • • Enter X-axis label in this cell For example: If you are graphing data for each day enter, “Date” in this cell If you are graphing data for each trial, enter “Trial” in this cell If you are graphing data for each session, enter “sessions” 2 Step 1: Set up the Variables X-Axis Step 1: Set up the Variables Y-Axis (AB design) For AB design, Enter Y-axis label in 2 cells alternating between the Baseline (A phase) and the Intervention (B phase) For example: • To graph data for Baseline phase and NCR using AB design, Label the cell B1 “Baseline” and cell C1 “NCR” 3 Step 1: Set up the Variables Y-Axis (AB design) Step 2: Enter the data X-Axis (AB design) Enter the dates, or trial or Session numbers in the column below the “X-axis label” Session number Date (Month/Day) Trial number 4 Step 2: Enter the Data Y-Axis (AB design) 11/10 2 11/11 3 11/12 3 11/13 1 11/14 2 Underneath the ‘‘Baseline’’ phase (cell B2) enter the data that correspond to the dates (or session/trial #s). This slide shows imputing our baseline data for frequency of “call outs” (per hour) before the NCR (IV) was implemented. Step 2: Enter the Data Y-Axis (AB design) Begin to enter the intervention phase data points from cell (C7) 11/15 3 11/16 3 11/17 2 11/18 1 11/19 2 11/20 0 11/21 0 11/22 0 In the ‘‘NCR’’ (intervention) phase (column C) enter the Intervention data that correspond to the dates (or session/trial #s) as it is shown in this slide. For example, to graph the NCR data for frequency of “call outs” (per hour), enter the first data point in cell C7. 5 AB Design Setup You Excel Worksheet Should look Like This Creating the Line Graph We are Ready to Create the Graph 6 Step 3: Create the Line Graph AB Design • Position the mouse on cell B1 • Click and hold the left mouse button • Move the mouse till all the data points are highlighted • Release the left button • If data collection for reimplementation of the intervention is ongoing, highlight additional empty cells. For example: if the data collection for implementation of NCR is going to continue for additional 7 days, cells 25 to 31 will be highlighted as well. Step 3: Create the Line Graph AB Design Click on Graph Icon 7 Step 3: Create the Line Graph For All Designs Click on Line graph Icon Then Click “Next” Step 3: Create the Line Graph For All Designs Click on Series 8 Step 3: Create the Line Graph For All Designs Click inside of (X) Axis labels box • Position the mouse on cell A2 • Click and hold the left mouse button • Move the mouse till all the cells highlighted for the data points are selected (move from A2 – A28) • Release the left button 9 Click Next> Step 3: Create the Line Graph Fill in the • Chart title: Chart for Talk outs • Category (X) axis: Date • Value (Y) axis: Frequency per Hour • Then click “Next” 10 Step 3: Create the Line Graph Click on Gridlines Step 3: Create the Line Graph Uncheck the Major gridlines 11 Click on Legend Uncheck Show legend Then click Next 12 Step 3: Create the Line Graph Click As new sheet then Finish Chart for Talk outs 13 Step 3: Create the Line Graph Adjust the X-axis When using Dates make the X-axis less cluttered by: 1. Clicking on any date on X-axis Step 3: Create the Line Graph Adjust the X-axis Make sure “Minor tick mark type” is checked Then click on Scale Tab 14 Step 3: Create the Line Graph Adjust the X axis 1. Change the Major unit to 5 2. Change the Minor unit to 1 3. Then click OK Step 3: Create the Line Graph Adjust the Y-axis 1. Click on any number on Y axis 15 Step 3: Create the Line Graph Adjust the Y-axis 1. Change the Maximum to a # that is larger than the highest number in data set. When Y axis is percentage set Maximum to 100 2. Change the Major unit to a whole number (e.g. 1 or 2) 3. Change the minor unit to a whole number (e.g. 1) 3. Then click OK Your “Format Axis” box should be similar to this 15 16 Chart for Talk outs Step 3: Create the Line Graph Adjust the Plot Area of the Graph Chart for Talk outs 1. Click anywhere on the graph 17 Step 3: Create the Line Graph Adjust the Plot Area of the Graph 1. Click on: Format Plot Area Step 3: Create the Line Graph Adjust the Plot Area of the Graph 1. Click on: “None” under Border and Area 2. Then click OK 18 Chart for Talk outs Step 4: Create the Line Graph Adjust the Points, Label the Phases and Draw the Phase change lines Chart for Talk outs 19 Step 4: Create the Line Graph Adjust the Points 1. Double Click on a point in baseline condition Step 4: Create the Line Graph Adjust the Points 1. Change the color of the lines to black 2. Change the style of the point to circle 3. Change the foreground of the points to black 4. Change the Background of the points to black Increase the size of the point (between 6-8) 20 Step 4: Create the Line Graph Adjust the Points Click OK 1. Follow the previously described procedure with intervention data points 21 Chart for Talk outs Step 4: Create the Line Graph Draw the Phase Change Lines Chart for Talk outs 1. Click on the Line icon 22 Step 4: Create the Line Graph Draw the Phase Change Lines 2. Draw the Lines by placing The mouse (+) on the X axis and, while pressing the left side of the mouse, move the mouse up. Chart for Talk outs 23 Step 4: Create the Line Graph Change the format of Phase Change Lines 1. Click on the Line to change the format Step 4: Create the Line Graph Change the format of Phase Change Lines Click on Dashed arrow and then choose Changes the thickness of the line 24 Step 4: Create the Line Graph Label the Phases 2. Move the Mouse to the middle of the Baseline phase and then right click 1. Click on Text Box Icon 25 Step 4: Create the Line Graph Label the Phases Type the Name of the Phase (Baseline) Do the same process with intervention phase • Click on Text box, Move the mouse the middle of the phase, right click and then type the name of the phase (e.g. NCR) Your Graph is Ready to be Printed Chart for Talk outs Baseline NCR 26
