A Punnett square is also used to determine the phenotypic ratio of the offspring. A phenotypic ratio is the ratio of visible traits displayed in the offspring. The Punnett square in Figure 4 shows the different allele combination and the phenotypic ratio that will result when two heterozygous parents are crossed.
The average typing speed is 38-40 words per minute (wpm) for adults in a professional working environment (despite many incorrect reports on the web that it is 50-60 wpm). <br /> <br /> Some administrative assistants can type 70-80 wpm or more.
For example, a score of 53 words per minute with 15 errors would be lower on the list than a score of 53 words per minute with 2 errors. THE RESULTS Figure 1 shows the distribution of all typing speed scores. Since our Mean was 40 and our Median 38, our statistically average typist is between 38 and 40 WPM. Someone who typed 56 is in the top 20% of all typists in the sample. A score of 65 is in the top 10% of the sample.
