The point of this lab is to learn about systematic errors, which occurs when a mistake happens when setting up an experiment. When a systematic error occurs the accuracy of the experiment is thrown off. The point of the experiment was to figure out the relationship between precision and accuracy.
The apparatus used in this experiment was a meter stick. I collected data for this experiment by clicking on one end of the meter stick then clicking on the other end. I did this over and over again until I had done this 20 times. The independent variable for this experiment was the number of the measurement. The dependent variable depends on where I clicked on the measuring stick.
The date for this experiment includes 10 different measurements from
There were no significant error factors that may have affected the arrangement of the lab experiment. Everything went smoothly with relative ease.
The laboratory experiment gives the experimenter a greater chance to control the conditions and enables you to measure behaviour with greater precision. This method also allows for quantative research and also enables greater control of variables. Although it gives the experimenter greater control, this can also seem daunting to the subject who may feel more uncomfortable and is less likely to ...
Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. The molars range from 1-3.
Question/Purpose : The purpose of this lab was to learn how construct and analyze graphs by figuring out the speed of the buggy car. The question was simple: did the buggy car maintain a constant speed throughout its movement. We will be changing the distance the car has to move and will be recording how long the car takes to move that distance. Therefore, distance is the independent variable while the time would be the dependant variable.
The dependent variable that will be measured is the height at which the ball bounces back. The control variables that will need to be kept constant if the results are to be as accurate as possible are. 1. What is the difference between a. and a. The weight of the ball; we will use the same ball throughout the experiment to ensure that the results are as accurate as possible.
For instance, in this experiment adding less of a substance’s mass to water will impact the crystal’s size by not making the width of a crystal not as large. The independent variable and the dependent variable do relate to one another. As stated above, the independent variable is the mass of a substance that was added to water, and the dependent variable is width of the crystals that will grow after seven days. The two variables do relate, because adding less or extra mass of a substance to a recipe did conflict with the data that was collected in the seven days that the crystal was
The Independent variable in this scenario is making use of Cheerios as targets for boys during toilet training.
1. Purpose and scientific goals The purpose of doing this lab is to observe and examine the different changes we see every day in the sky. Italian astronomer Galileo Galilei created a perfect method that could be useful for measuring time. The object or tool used in this lab is called a pendulum.
In this experiment, I skied down a slope without turning and measured my final velocity at the end of the slope. The independent variable in this experiment was my cross sectional area and the dependent variable was the final velocity at the end of the slope.
The tennis ball is the constant variable factor (the variable that is kept the same, to make the investigation valid). The ball will dropped from increasing heights (cm-25, 50, 75,100,125,150,175,200) and the bounce of the ball will be measured. A sample size of 3 results will be taken from each height the ball is dropped. The same investigation will then be repeated, but one of the independent variables will be changed.
... point was subjective; however it would have been a systematic error because I consistently judged the end point of my experiment. To eliminate this inaccuracy I should have used a colorimeter to judge the end point of my experiment.
The purpose of the first study was to do two things. To demonstrate a tech...
It is difficult to accurately measure this, and so I will see the amount of water that is collected in the beaker in a fixed amount of time (5 seconds). Hence the dependent variable is the volume collected in the beaker in 5 seconds. The unit of measurement would be milliliters per second (mL/s)
Imagine that you are going to design and perform the experiment described in the dialogue.
The purpose of this experiment was to understand how different variables can affect the period of oscillation of a pendulum.
