A particle has a particular life span of time t. if the particle moves very fast, relative to a stationary observer, the observer will observe that the life span of the particle is greater than t. If the observer moves toward the source at a speed vo, more waves are intercepted per second and the frequency received by the observer increases.
If the observer is stationary, the frequency received by the observer equals the frequency produced by the source. The measured frequency rises above the source frequency as the observer approaches the stationary source. The observed frequency is lower than the source frequency.

So many differences, can't focus on what is important due to this large within-group variance can obscure a between-groups difference.
within-groups variance (from time to time referred to as error institution or error variance) is a term utilized in ANOVA checks. It refers to versions due to variations within man or woman corporations (or degrees). In other words, no longer all the values within every group (e.g. method) are equal.
By means of dividing the experimental conditions into numerous "blocks", the researcher can localize error variance i.e. in each block the inside group's variance is smaller. for example, in an test a researcher accrued the information in days.
