How do you find the volume of a bolt?
measure it in a graduated cylinder
1 sqmt is equal to how many ft?
There can be no equivalence. A foot is a measure of length in 1-dimensional space while a square metre is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
Measure cubic meter?
Cubic meter is a measure of volume. If you have pure water, then 1 cubic meter weighs 1000 kilograms or 1 tonne. 1 cubic meter is also 1000 liters.
If the polygon is regular what is the size of each interior angle?
this depends on what type of polygon it is.. if it is a regular triangle, then all interior angles measure up to 180 degrees. So, a triangles interior angles would measure 60 degrees each.
What measures are used to describe variability?
Generally, the standard deviation (represented by sigma, an O with a line at the top) would be used to measure variability. The standard deviation represents the average distance of data from the mean. Another measure is variance, which is the standard deviation squared. Lastly, you might use the interquartile range, which is often the range of the middle 50% of the data.
You know the minimum the maximum and the 25th 50th and 75th percentiles of a distribution. what measures of central tendency or variability can you determine?
With the minimum, maximum, and the 25th (Q1), 50th (median), and 75th (Q3) percentiles, you can determine several measures of central tendency and variability. The median serves as a measure of central tendency, while the interquartile range (IQR), calculated as Q3 - Q1, provides a measure of variability. Additionally, you can infer the range (maximum - minimum) as another measure of variability. However, you cannot calculate the mean without more information about the data distribution.
What is the interquartile range a measure of?
The interquartile range is well known as a measure of statistical dispersion. It is equal to difference between upper and lower quartiles. The quartiles is a type of quantile.
Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.
Why is Interquartile range important?
It is important in any statistic measure
How do you interpret the interquartile ratio?
The interquartile ratio (IQR) is a measure of statistical dispersion that represents the range within which the central 50% of a data set lies, calculated as the difference between the third quartile (Q3) and the first quartile (Q1). It is useful for understanding the spread and variability of data while being resistant to outliers. A higher IQR indicates greater variability, while a lower IQR suggests that the data points are more closely clustered around the median. Overall, the IQR provides insight into the distribution of the middle half of the data.
Is the most common encountered measure of variability standard deviation?
The most commonly encountered measure of variability is indeed the standard deviation, as it provides a clear indication of how much individual data points deviate from the mean in a dataset. It is widely used in statistical analysis because it is expressed in the same units as the data, making it easy to interpret. However, other measures of variability, such as range and interquartile range, are also important and may be preferred in certain contexts, particularly when dealing with non-normally distributed data or outliers.
Is range a measure of variability?
Yes. The greater the range, the greater the variability.
What is a inter quatile range?
The interquartile range (IQR) is a measure of statistical dispersion, or spread, that provides information about the middle 50% of a dataset. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) and is useful for identifying outliers and understanding the variability of the data.
What is the semi interquartile range?
The semi interquartile range is a measure for spread or dispersion. To find it you have to subtract the first quartile from Q3 and divide that by 2, (Q3 - Q1)/2
What does interquartile range mean?
The interquartile range is the upper quartile (75th percentile) minus (-) the lower percentile (75th percentile). The interquartile range uses 50% of the data. It is a measure of the "central tendency" just like the standard deviation. A small interquartile range means that most of the values lie close to each other.
What is the best measure of center and measure of variation (spread) to use with a data set that has an outlier?
When a data set has an outlier, the best measure of center to use is the median, as it is less affected by extreme values compared to the mean. For measure of variation (spread), the interquartile range (IQR) is preferable, since it focuses on the middle 50% of the data and is also resistant to outliers. Together, these measures provide a more accurate representation of the data's central tendency and variability.
