Which measure is always the same as the 25th percentile?
lower quartile
What is the measure of quartile deviation?
A quartile deviation from some specified value, is the value or values such that a quarter of the observed values fall between these values and the specified value. Usually, but not always, the specified value is the median - the value such that have the observed values are below (and above) it. In that case, one quartile values will have a quarter of the values below it and the other will have a quarter of the values above it. The quartile deviations will be the differences between median and the two quartiles just calculated.
Will the quartile always be 25 percent 50 percent and 75 percent?
Yes. The prefix "quart" is derived from the word for 4, so quartile always means splitting the data into 4 sections, ie. 25%, 50%, 75%, 100%.
Uniformity coefficient of soil is always less than 1?
The uniformity coefficient (Cu) of soil is a measure of the particle size distribution, defined as the ratio of the size of the 60th percentile of the grain size distribution to the size of the 10th percentile. For a well-graded soil, Cu is greater than 1, indicating a range of particle sizes, while a uniform soil with similar particle sizes will have a Cu value close to 1. Therefore, the statement that the uniformity coefficient of soil is always less than 1 is incorrect; it can be equal to 1 or greater than 1 depending on the soil's grading.
Is the sum of the measure of an acute angle and the measure of an obtuse angle always greater than 180 degree?
Not not always since an obtuse angle is always greater than 90 degrees and an acute angle is always less than 90 degrees.

Why is the range always greater than the IQR?
Because the IQR excludes values which are lower than the lower quartile as well as the values in the upper quartile.
Does a negative z score always yield a negative percentile?
A percentile is always between 0% and 100%, never negative.
Will the quartile always be 25 percent 50 percent and 75 percent?
Yes. The prefix "quart" is derived from the word for 4, so quartile always means splitting the data into 4 sections, ie. 25%, 50%, 75%, 100%.

For which measure of central tendency will the sum of the deviations always be zero?
Can you always measure the length of a line?
no
What is constant 250?
A measure that is always 250.
Is it better to measure by weight or cups when baking?
It is always better to measure by WEIGHT when baking.

In a triangle the angle with the smallest measure is always opposite the?
shortest side
