Introduction of Your Lab Report It could be anywhere from three or four paragraphs to a couple pages long, depending on the complexity of the topic and, of course, the requirements of your instructor.

## What tense are lab reports written?

present tense

## Are lab reports written in third person?

In order to convey an objective scientific point of view, lab reports are written in the third person passive voice, instead of the first person active voice. By doing this, the focus shifts from the experimenter to the experiment itself.

## What should be included in a lab introduction?

Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don’t write a whole introduction, you need to state the purpose of the experiment, or why you did it.

## How do you describe a graph in a lab report?

A graph should be labeled as a Figure, not a Table. The title of the figure should include enough detail that the image could “stand alone” without having to read too much of the paper. Click on the question, to see the answer.

## How do you caption a lab report on a graph?

Figures should be labeled with a number followed by a descriptive caption or title. Captions should be concise but comprehensive. They should describe the data shown, draw attention to important features contained within the figure, and may sometimes also include interpretations of the data.

## How do you describe a graph?

Describing language of a graph

- UP: increase / rise / grow / went up / soar / double / multiply / climb / exceed /
- DOWN: decrease / drop / fall / decline / plummet / halve / depreciate / plunge.
- UP & DOWN: fluctuate / undulated / dip /
- SAME: stable (stabilised) / levelled off / remained constant or steady / consistent.

## What are 3 things a graph must have?

Essential Elements of Good Graphs:

- A title which describes the experiment.
- The graph should fill the space allotted for the graph.
- Each axis should be labeled with the quantity being measured and the units of measurement.
- Each data point should be plotted in the proper position.
- A line of best fit.

## How do you introduce a graph?

To catch your audience’s attention from the very beginning, you can use the following phrases for introduction:

- Let me show you this bar graph…
- Let’s turn to this diagram…
- I’d like you to look at this map…
- If you look at this graph, you will notice…
- Let’s have a look at this pie chart…

## How do you tell if a graph is a function?

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

## How do you determine if its a function?

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

## How do you determine a function?

How To: Given a relationship between two quantities, determine whether the relationship is a function.

- Identify the input values.
- Identify the output values.
- If each input value leads to only one output value, classify the relationship as a function.

## What is not a function?

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

## What is an example of not a function?

Vertical lines are not functions. The equations y=±√x and x2+y2=9 are examples of non-functions because there is at least one x-value with two or more y-values.

## Which set is a function?

A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function.
