Inhoudsopgave
Wat is de grootste voorspeller voor een verhoogd valrisico?
Mobiliteitsstoornissen, bestaande uit stoornissen in balans, looppatroon en/of spierkracht, zijn één van de belangrijkste risicofactoren voor vallen (CBO, 2004; NICE, 2013; Deandra, 2010).
What is a p-value?
What exactly is a p -value? The p-value, or probability value, tells you how likely it is that your data could have occurred under the null hypothesis. It does this by calculating the likelihood of your test statistic, which is the number calculated by a statistical test using your data. The p -value tells you how often you would expect
How to find p-value from z-score?
How to find p-value from Z-score? In terms of the cumulative distribution function (cdf) of the standard normal distribution, which is traditionally denoted by Φ, it is given by the following formulae: Left-tailed z-test: p-value = Φ(Z score) Right-tailed z-test: p-value = 1 – Φ(Z score) Two-tailed z-test: p-value = 2 * Φ(−|Z score |)
What is the significance of a p value?
Significance is usually denoted by a p-value, or probability value. Statistical significance is arbitrary – it depends on the threshold, or alpha value, chosen by the researcher. The most common threshold is p < 0.05, which means that the data is likely to occur less than 5% of the time under the null hypothesis.
What does it mean if the p-value is high or low?
A high p-value means that your data is highly compatible with the null hypothesis; and A small p-value provides evidence against the null hypothesis, as it means that your result would be very improbable if the null hypothesis were true. However, it may happen that the null hypothesis is true, but your sample is highly unusual!
Waaruit bestaat een Valanamnese?
1. Wat zijn de problemen? (stel dit vast in overleg met de cliënt/ wettelijk vertegenwoordiger. 2. Wat zijn de wensen/ verwachtingen van de cliënt/ wettelijk vertegenwoordiger ten aanzien van bovenstaande?
