Where are ogives used?
The word Ogive is a term used in architecture to describe curves or curved shapes. Ogives are graphs that are used to estimate how many numbers lie below or above a particular variable or value in data.
How do you mark a frequency polygon?
To draw frequency polygons, first we need to draw histogram and then follow the below steps:
- Step 1- Choose the class interval and mark the values on the horizontal axes.
- Step 2- Mark the mid value of each interval on the horizontal axes.
- Step 3- Mark the frequency of the class on the vertical axes.
What is the difference between ogive and frequency polygon?
The most important difference between them is that an ogive is a plot of cumulative values, whereas a frequency polygon is a plot of the values themselves. So, to get from a frequency polygon to an ogive, we would add up the counts as we move from left to right in the graph.
When should frequency polygons be used?
Frequency polygons are useful for comparing distributions. This is achieved by overlaying the frequency polygons drawn for different data sets.
What is TSC (time stamp counter) clock frequency?
What the TSC (Time Stamp Counter) clock frequency actually is, varies depending on the hardware, and may vary during runtime on some. To measure real time, you use clock_gettime (CLOCK_REALTIME) or clock_gettime (CLOCK_MONOTONIC) in Linux.
Does the time stamp counter count clock cycles or reference clock cycles?
As Peter Cordes mentioned in a comment (Aug 2018), on most current x86-64 architectures the Time Stamp Counter (accessed by the RDTSC instruction and __rdtsc () function declared in ) counts reference clock cycles, not CPU clock cycles.
How does the AMD time stamp counter work?
AMD processors up to the K8 core always incremented the time-stamp counter every clock cycle. Thus, power management features were able to change the number of increments per second, and the values could get out of sync between different cores or processors in the same system.
What are time stamps and time interval measurements?
Time stamps and time-interval measurements are an integral part of computer and network performance measurements. These performance measurement operations include the computation of response time, throughput, and latency as well as profiling code execution.
