What are 5 ways that graph can be misleading ?
2 answers:
There are many ways that graphs can be misleading. Depending on how you set up your graph, the same set of data can look very different. It's important to understand that there are some common mistakes to avoid when making graphs. In addition, advertisers have been known to intentionally make their graphs misleading to make their data match their point.
In the image provided, this is a good example of a misleading graph.
First, notice that we know that the first bar is 10 and the second bar is 50. However, there are no labels on the horizontal or vertical axis so we don't know what the bars represent.
In addition, notice that there is no title on this graph. Since there is no title on the graph, we don't know anything about the data.
Further, look at the scale on the vertical axis. Notice that it's an uneven scale. The uneven scale makes it appear that the first bar is closer to the second bar than it actually is.
We could correct this graph by adding labels to the x and y-axis, adding a title to the graph, and making the scale on the vertical axis even.
Another way graphs can be misleading is using the wrong type to represent data. For example, a scatter plot might be better than a regular graph in some cases.
Lastly, graphs can be misleading by adding a wide range of numbers to show and increase or decrease relatively small to how it actually is.

Given the expression,
We will have to rationalize the denominator first. To rationalize the denominator we have to multiply the numerator and denominator both by the square root part of the denominator.
If we have , we will get
by multiplying them. And
.
So here in the problem, we will get,
Now in the numerator we have . We can check 8x is common there. we will take out -8x from it, we will get,
And in the denominator we have . We can check 2 is common there. If we take out 2 from it we will get,
So we can write the expression as
is common to the numerator and denominator both, if we cancel it we will get,
We can divide -8 by the denominator, as -8 os divisible by 2. By dividing them we will get,
So we have got the required answer here.
The correct option is the last one.
