To plot the number 1.5 on a logarithmic scale, let's break down the steps.

1. The number 1.5 is between $10^0$ and $10^1$ on a log scale.
2. $10^0$ is 1, and $10^1$ is 10, so 1.5 falls between these two points.
3. Since logarithmic scales are not linear, we estimate the position by understanding that 1.5 is closer to 1 than to 10.

On a log scale, 1.5 would be plotted slightly to the right of the point representing $10^0$, but still quite close to it. If you have a marking option, place the point just right of $10^0$ on the line.

2. How do you plot other numbers like 0.5 or 5 on a logarithmic scale?
3. Why are logarithmic scales useful in data visualization?
4. How would you calculate the position of 2.5 on this same scale?
5. Can we plot negative numbers on a logarithmic scale, and why?

Tip: When plotting on a log scale, remember that each "tick mark" represents a power of 10, not an equal interval, making positioning relative rather than exact without calculation.
