Multiple response variables - a set of response variables which are all affected by the same independent variable . Learning Outcomes. As a result of watching and studying this video lesson, you could go on to: Define response variable and explanatory variable ; Illustrate each type of variable with a hypothetical experiment
Measure the shelves with a tape measure. Get the width and depth at the widest points and mark them down on a piece of paper. Place the shelf liner face down on a solid surface and mark the correct area to cut. Use a tape measure or ruler to draw a straight line if the liner does not have grids to follow.
Step 2: Using an electronic detector, check that the area of wall where you plan to hang the shelves is free from hidden pipes or cables. Step 3: Place your first bracket against the wall, using a spirit level to make sure it's level. Mark the fixing-hole positions with a pencil.Step 4: Using the pencil marks, drill holes into the wall.crew the bracket into place. Step 5: Slide the shelf onto the bracket to check that it's level (use the spirit level to make sure). Once you're happy with the position of this shelf and the way it looks, slide it back off the bracket so that you can position the rest of the brackets.
