Answer:
12.5 is to the nearest tenth
12.54 is to the nearest hundredth
Step-by-step explanation:
12.537
The first number after the decimal is the tenths place
we look at the number after it to determine whether to round up or down
12.53 the 3 is less than 5 so we leave it alone
13.5 is rounded to the nearest tenth
The second number after the decimal is the hundrdeths place
we look at the number after it to determine whether to round up or down
12.537 the 7 is greather than or equal to 5 so we round up
13.537 is rounded becomes 13.54
The appropriate measure of variation (spread) for these data points is "Standard deviation."
<h3>What is Standard deviation?</h3>
The standard deviation would be a statistic that calculates as the square root of the variance and measures the distribution of a set of data relative to its mean.
Some key features regarding the Standard deviation are-
- The standard deviation is determined as the square root of the variance by determining the deviation of each data point from the mean.
- In finance, standard deviation is frequently employed as an assessment of an asset's relative riskiness.
- A volatile stock does have a high standard deviation, whereas a stable blue-chip stock has a low deviation.
- The standard deviation, on the other hand, calculates those ambiguity as risk, even when it is in the investor's favor, like above-average returns.
