question 2 What happens when you log transform the dependent

question 2 What happens when you log transform the dependent data in an exponential growth curve?

a.)It becomes a straight line

b.)It becomes undefined

c.)It becomes a parabola d.)It becomes a line curving in the opposite direction

Question 2 Which of the following will result in graphs that have the same shape:

a.)a graph of the untransformed data (on regular paper) and a graph of log-transformed data (on semi-log paper).

b.)a graph of the log-transformed data (on regular paper) and a graph of log-transformed data (on semi-log paper)

c.)a graph of the log-transformed data (on regular paper) and a graph of untransformed data (on semi-log paper).

Question 3 You are making a graph on semi-log paper. If you label the first cycle 1000, which of the following is true:

a.)the second cycle will be 10,000 and the first tick between 1000 and 10,000 will be 1500.

b.)the second cycle will be 2000 and the first tick between 1000 and 2000 will be 1100.

c.)the second cycle will be 10,000 and the first tick between 1000 and 10,000 will be 2000.

Question 4 Click all items below that are true of log-transformations

a.)It always converts curved lines into straight lines

b.)It is usually useful, regardless of what kind of data you have

c.)It can help \"unsquish\" a graph

d.)It converts exponential growth curves into straight lines

Question 5 If your data spans the range 100 to 4500, what kind of semi-log paper will you need?

a.)1 cycle

b.)4.5 cycles

c.)3 cycles

d.)2 cycles

Question 6 If your data spans the range 2 hundred to 2 million, what kind of semi-log paper will you need?

a.)it doesn\'t matter how many cycles, because you can label them however you want

b.)5 cycles

c.)3 cycles

d.)2 cycles

Solution

1. It will become a straight line. Therefore, option (a) is correct.

2. Graph of log transformed data on regular paper and the graph of untransformed data on semi-log paper are both equal. Therefore, option (c) is correct.

3. The second cycle will be 10,000 and the first tick between 1000 and 10,000 will be 2000. Therefore, option (c) is correct.

4. Log transform converts exponential growth curve into straight lines. Therefore, option (d) is correct.

5. We will need 2 cycle semi log paper in order to span 100 to 4500. Therefore, option (d) is correct.

6. We will need 5 cycle semi log paper in order to span 2 hunder to 2 million. Therefore, option (b) is correct.

5. (d) 2 cycles
