Figure 1. Bar chart with a summary statistic We can observe the following: Based on the height of the bars, it is clear that the mean salary for males is greater than the mean salary for females. The scale forsalarybegins at 0. This is appropriate for this chart. Using a different min...
A z-score, or z-statistic, is a number representing how many standard deviations above or below the mean population the score derived from a z-test is. Essentially, it is a numerical measurement that describes a value's relationship to the mean of a group of values. If a z-score is 0...
# Run the display ipfpm statistic-type loss instance 1 command on Switch_2 that functions as the MCP to view the packet loss measurement result. <Switch_2> display ipfpm statistic-type loss instance 1 Latest loss statistics of forward flow: Unit: p - packet, b - byte --- Period Loss...
The test statistic’s value, the critical value, and the confidence intervals are used to conclude. Below are a few significant hypothesis tests that are employed in inferential statistics.Z Test When data has a normal distribution and a sample size of at least 30, the z test is applied to...
A user operates TCP applications on the application client, for example, website visiting, remote Telnet login, and FTP file operation. The user wants to know the network statistics such as network delay and packet loss rate of TCP applications, so the user enables TCP FPM on the router to...
t-distribution used int-testswhen calculating the p-value. Depending on the sample size, different degrees of freedom will display different t-distributions. Calculating degrees of freedom is critical when understanding the importance of a chi-square statistic and the validity of the null hypothesis....
At first glance, a sample statistic and a population parameter might seem very similar because they are both providing a descriptive measure of a population. However, there is a difference between parameters and statistics. In fact, there are many differences.Parameter...
Then, run the display traffic policy statistics interface gigabitethernet 0/0/1 inbound command to check the traffic statistics on the interface. If the configuration is successful, all packets sent at the rate of 1500...
# Create a flexible flow statistics template named test, configure aggregation based on the destination IP address and destination port number, configure the number of bytes and packets in the exported packets, and configure the indexes of the inbound and outbound interfaces. [Router...
Cross-correlation is a measurement used in statistics. It is a method of measuring the relative degree of similarity or dissimilarity between two variables. How Is Cross-Correlation Useful? Consider a stock investor who owns a technology stock that has been performing well. The investor might want...
