4. Benchmark and keep measuring.Your NPS score is only useful if you measure it consistently over time. So, begin by remembering your current result and use that as a basis to grow. It’s the only way to get an accurate sense of how you’re performing in the long run. Let’s tackl...
It is in continuous form, and frequency distribution is given in the form of a table. The median of such data is calculated by the formula: Median = L + ((n/2 – CF)/f) x w Where, l= lower class limit, n is the total frequency, CF is the cumulative frequency up to the ...
NPS is all about the score you get by subtracting the percentage of detractors from the percentage of promoters. However, you can get valuable insights from the individual survey score distribution. Just think about it: a detractor who chose “1” will be much different from the one who chose...
Chi-Square Distribution | Definition, Graph & Examples from Chapter 1 / Lesson 25 36K Learn what Chi-square distribution, also known as the X^2 distribution, is. Understand the Chi-square graph and find Chi-square distribution examples. Related...
Multimidal distributions have more than two peaks. If you can’t clearly find one peak or two peaks in a graph, the likelihood is that you either have auniform distribution(where all the peaks are the same height) or a multimodal distribution, where there are several peaks of the same he...
What z-score has 2.5% of the normal distribution below it? A normal distribution has a mean of 98 and a standard deviation of 6. What is the probability that a randomly selected x-value from the distribution is at least 80? Given a normal distribution, the population mean is 65 and the...
Predictive analytics can do much of the work of generating a credit score or deciding whether a straightforward insurance claim can be paid out. In healthcare, predictive analytics can be used to automatically map the likely success rates for new treatments, identify patients that would benefit, ...
score of 0.2 is a small effect, 0.5 is a medium effect, and 0.8 is a large effect. The other effect size is eta-squared, with measures the strength of the relationship between two variables. For eta-squared, a score of .05 is a weak effect, .10 is a medium effect, and .15 is ...

Uniform Distribution has a constant probability. It is important to practice examples of uniform distribution after learning it’s formulas. The Uniform distribution is denoted by X U (a,b).
